in java Integer numVals is read from input and integer array userScore is declared with size numVals. Then, numVals integers are read from input and stored into userScore. Replace the last element in userScore with -1. Ex: If the input is: 4 93 94 9 42 then the output is: Updated scores: 93 94 9 -1

Part 1: In Java Write a program that uses a 2-D array to store the highest and lowest temperatures for each month of the year. The program should output the average high, average low, and highest and lowest temperatures of the year. Your program must consist of the following methods with their appropriate parameters: a.) getData: This method reads and stores the data in the 2-D array. b.) averageHigh: This method calculates and returns the average high temperature of the year. c.) averageLow: This method calculates and returns the average low temperature of the year. d.) indexHighTemp: This method returns the index of the highest temperature in the array. e.) indexLowTemp: This method returns the index of the lowest temperature in the array. Use the following input: High temp for each month: 30 40 45 60 70 90 89 95 79 90 70 40 Low temp for each month: 10 -10 20 30 50 75 85 79 50 80 30 20
Computer Science Java Program Write a program in Java that takes in a user-submitted file that is a grid of 0s and 1s. Represent the grid as a two-dimensional array. Write a program that: a. computes the size of a group when a square in the group is given b. computes the numbers of different groups c. lists all groups Example: userInput.txt: 0 0 0 0 0 0 0 0 0 10 0 0 1 1 0 0 0 0 10 0 0 0 0 0 0 0 0 00 0 0 0 1 0 0 1 0 00 0 0 1 0 0 0 1 0 00 0 0 0 0 0 0 1 1 00 0 0 0 1 1 0 0 0 00 0 0 0 0 0 0 0 0 00 0 0 0 0 0 0 0 0 00 0 0 0 0 0 0 0 0 0 The program should output three things: The size of the group in which location specified by the user belongs. then if the user enters 1,2 the answer is 0 1,4 the answer is 2 3,4 the answer is 1 4,7 the answer is 4 The number of each size group Size Count 2 3 1 List of each group’s locations 1: (0,9) (1,9) 2: (1,3) (1,4) 3: (3,4) 4: (3,7) (4,7) (5,7) (5,8) 5: (4,3) 6: (6,4) (6,5)
in java Integer numVals is read from input and integer array userCounts is declared with size numVals. Then, numVals integers are read from input and stored into userCounts. If the first element is less than the last element, then assign Boolean firstSmaller with true. Otherwise, assign firstSmaller with false. Ex: If the input is: 5 40 22 41 84 77 then the output is: First element is less than last element 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 import java.util.Scanner; public class UserTracker { publicstaticvoidmain(String[] args) { Scannerscnr=newScanner(System.in); intnumVals; int[] userCounts; inti; booleanfirstSmaller; numVals=scnr.nextInt(); userCounts=newint[numVals]; for (i=0; i<userCounts.length; ++i) { userCounts[i] =scnr.nextInt(); } /* Your code goes here */ if (firstSmaller) { System.out.println("First element is less than last element"); } else { System.out.println("First element is not less…
JAVA program Write a Java program that asks the user to enter an array of integers. The program should prompt the user for the number of elements in the array and then the elements of the array. The program should then call a method named minGap that accepts the array entered by the user as a parameter and returns the minimum 'gap' between adjacent values in the array. The main method should then print the value returned by the method. The gap between two adjacent values in an array is defined as the difference in value between the first element and the second element. For example, suppose the user entered the following array of integers {1, 3, 6, 5, 12} The first gap is 2 (3 - 1), the second gap is 3 (6 - 3), the third gap is 1 (6 - 5) and the fourth gap is 5 (12 - 6). Thus, the call of minGap(array) should return 1 because that is the smallest gap in the array. If you are passed an array with fewer than 2 elements, you should return 0. Use Math.abs()
in java Integer numVals is read from input and integer array userCounts is declared with size numVals. Then, numVals integers are read from input and stored into userCounts. Output all elements of userCounts in reverse order, following each element with a space, including the last. After the final output, end with a newline. Ex: If the input is 4 54 56 75 7 then the output is: Array contents in reverse: 7 75 56 54 Note: The loop should start with i = userCounts.length - 1 and end with i = 0. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 import java.util.Scanner; public class UserLog { publicstaticvoidmain(String[] args) { Scannerscnr=newScanner(System.in); intnumVals; inti; numVals=scnr.nextInt(); int[] userCounts=newint[numVals]; for (i=0; i<userCounts.length; ++i) { userCounts[i] =scnr.nextInt(); } System.out.print("Array contents in reverse: "); /* Your code goes here */ } }
Declare an array that represents 100 students. Assign the examscores between 0 and 100 randomly into this array. Write amethod and display that assigns letter grade equivalents of theexam scores to a second array. Display the number ofunsuccessful students.The grade scala is as follows:100 – 90 : A89 – 80 : B79 – 70 : C69 – 60 : D59 – 0 : F (unsuccessful) (Write in java)

Functions with 2D Arrays in Java Write a function named displayElements that takes a two-dimensional array, the size of its rows and columns, then prints every element of a two-dimensional array. Separate every row by a new line and every column by a space. In the main function, call the displayElements function and pass in the required parameters. Output 1 2 3 4 5 6 7 8 9
in java Integer numElements is read from input, representing the number of integers to be read next. Then, the remaining integers are read and stored into array valuesArray. For each element in valuesArray that is divisible by 9, assign the element with the element's current value plus 1. Ex: If the input is: 3 81 99 30 then the output is: Original values: 81 99 30 New values: 82 100 30 Note: (x % 9 == 0) returns true if x is divisible by 9. 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 for (i=0; i<valuesArray.length; ++i) { valuesArray[i] =scnr.nextInt(); } System.out.print("Original values: "); for (i=0; i<valuesArray.length; ++i) { System.out.print(valuesArray[i] +" "); } System.out.println(); /* Your code goes here */ System.out.print("New values: "); for (i=0; i<valuesArray.length; ++i) { System.out.print(valuesArray[i] +" "); } System.out.println(); } }
in Java please This program will store roster and rating information for a soccer team. Coaches rate players during tryouts to ensure a balanced team. (1) Prompt the user to input five pairs of numbers: A player's jersey number (0 - 99, but this is NOT enforced by the program nor tested) and the player's rating (1 - 9, not enforced like jersey numbers). Store the jersey numbers in one int array and the ratings in another int array. Output these arrays (i.e., output the roster) as shown below after inputting the data. Ex Enter player 1's jersey number: 84 Enter player 1's rating: 7 Enter player 2's jersey number: 23 Enter player 2's rating: 4 Enter player 3's jersey number: 4 Enter player 3's rating: 5 Enter player 4's jersey number: 30 Enter player 4's rating: 2 Enter player 5's jersey number: 66 Enter player 5's rating: 9 ROSTER Player 1 -- Jersey number: 84, Rating: 7 Player 2 -- Jersey number: 23, Rating: 4 . . .
