Expert Solution & Answer
Explanation of Solution
Method:
A collection of statements which are formed together to perform an operation is called as method.
Declaration of a method:
Method declaration gives the description of what the method should perform; Method declaration holds the modifier, return type, name of the method, the list of parameters and the body of the method.
Syntax for defining a method:
modifier return_type methodName(list of parameters)
{
//body
}
Example:
public int findArea(int x, int y)
{
//body
}
The above statement shows the declaration of the method; here,
- public – modifiers
- int – return type
- findArea – name of the method
- x, y – formal parameters
- int x, int y – list of parameters
- Body is the part of the method that contains the statements and the operations to be performed.
Braces:
- Braces usually enclose the number of statements.
- In a function, the numbers of statements are enclosed within the braces.
- The opening of the function contains the open braces “{”.
- The ending of the function contains the close braces “}”.
