Example of with parameter and with return type Method

Prgm:This program will show method with parameter and with return type.here method takes two parameter and this method has a return type that's double.check the program here.

class MulOfNumber
{
//return type is double and method taking two double type parameter
double mul(double x,double y)
{
double result=x*y;
return result; //return result
}
}

class MethodExample
{
public static void main(String args[])
{
MulOfNumber sn=new MulOfNumber();
double z=sn.mul(5.2,2.5);
System.out.print("Result is : "+z);
}
}
O/P:Result is : 13.0

Example of Method without any parameter and without return type:

class Calculate

{

int num1,num2;

Calculate(int x,int y)

{

num1=x;

num2=y;

}

void sum()

{

int res=num1+num2;

System.out.println("Result is : "+res);

}

}

class methodWithoutParameter

{

public static void main(String args[])

{ 

Calculate c=new Calculate(21,44);

c.sum();

}

}

O/P:

Result is : 65
