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 “}”.
