Hi Let me knoiw if you need more information:-

=========================================

Before going to compile:-

1. check your files are there in current directory.

2.check java set in path [if not set in path]

3.check class path set to current directory [CLASSPATH=.;]

4. check the permission of the files.

========================================

Calculate.java

===========================================

public class Calculate {

public static int addition(int input1, int input2) {
return ((input1 + input2));
}

public static int subtraction(int input1, int input2) {
return ((input1 – input2));
}

public int multiply(int input1, int input2) {
return ((input1 * input2));
}

public int division(int input1, int input2) {
return ((input1 / input2));
}
}

===========================

Lab2.java

===============================

public class Lab2 {

public static void main(String[] args) {

int input1 = 0;
int input2 = 0;
try {
input1 = Integer.parseInt(args[0]);
input2 = Integer.parseInt(args[1]);
} catch (Exception e) {
System.out.println(“Please Enter Valid Input values”);
}

System.out.println(“Addition Result: ” + Calculate.addition(input1, input2)); // Static method can be called using class reference
System.out.println(“Subtraction Result: ” +Calculate.subtraction(input1, input2));// Static method can be called using class reference
Calculate calculate = new Calculate();// Create object to access non static methods
System.out.println(“Multiplication Result: ” +calculate.multiply(input1, input2));
System.out.println(“Division Result: ” +calculate.division(input1, input2));

}

}

===========================================

OUTPUT:-

=========================================
