Parameter Method in Java

Java Method Parameters

Parameters are variables defined in the method declaration after the method name, inside the parentheses. This includes primitive types such as int, float, boolean, etc, and non-primitive or object types such as an array, String, etc.

Today day class is parameters method topic taken in the class .

1. What is a Parameter in a Method

A parameter is a variable in the method definition that accepts a value (called an argument) when the method is called.

Types of Parameters
Formal Parameters
Defined in the method declaration.
Example: int a, int b in add(int a, int b)

*Actual Parameters *(Arguments)
Passed when calling the method.
Example: add(5, 3) – here 5 and 3 are actual parameters.

Today complete my task
class Hello {

int num1;
int num2;
int num3;

Hello(int x,int y, int z) {
num1 = x;
num2 = y;
num3 = z;

}
int addTwo(){
return num1 + num2;
}
int addThree(){
return num1 + num2 + num3;
}

int subTwo(){
return num1 - num2;
}
int subThree(){
return num1 - num2 - num3;
}
int multiplicationTwo(){
return num1 * num2;
}
int multiplicationThree(){
return num1 * num2 * num3;
}
int diviTwo(){
return num1 / num2;
}
int diviThree(){
return num1 / num2 / num3;
}
int modulusTwo(){
return num1 % num2;
}
int modulusThree(){
return num1 % num2 % num3;
}
void displayDetails(){

    System.out.println("Numbers: " + num1 + " , " + num2 + " , " + num3);

    System.out.println("Add num1 + num2 = " + addTwo());

    System.out.println("Add num1 + num2 + num3 = " + addThree());

    System.out.println("Sub num1 - num2 = " + subTwo());

    System.out.println("Sub num1 - num2 - num3 = " + subThree());

    System.out.println("Multiplication num1 * num2 = " + multiplicationTwo());

    System.out.println("Multiplication num1 * num2 * num3 = " + multiplicationThree());

    System.out.println("Divi num1 / num2 = " + diviTwo());

    System.out.println("Divi num1 / num2 / num3 = " + diviThree());

    System.out.println("Modulus num1 % num2 = " + modulusTwo());

    System.out.println("Modulus num1 % num2 % num3 = " + modulusThree());

}
}

public class Calcul {
public static void main(String args[]){

Hello h1 = new Hello(414,524,656);
h1.displayDetails();
}
}

output

Numbers: 414 , 524 , 656
Add num1 + num2 = 938
Add num1 + num2 + num3 = 1594
Sub num1 - num2 = -110
Sub num1 - num2 - num3 = -766
Multiplication num1 * num2 = 216936
Multiplication num1 * num2 * num3 = 142310016
Divi num1 / num2 = 0
Divi num1 / num2 / num3 = 0
Modulus num1 % num2 = 414
Modulus num1 % num2 % num3 = 414
