Java program to subtract two number
Code to subtract two integer number using method
The program allows to enter two integer values then, it calculates subtraction of the given two numbers
Program 1
import java.util.Scanner;
public class SubTwoNumbers{
public static void main(String args[]){
Scanner scan=new Scanner(System.in);
//create a scanner instance for receives input
// from the user - input from keyboard
System.out.print("Enter Two numbers for subtraction: ");
int num1=scan.nextInt();
int num2=scan.nextInt();
//reads the numbers from the user
//input from keyword
calcSub(num1,num2);//call the metohd
}
static void calcSub(int x, int y){ //Define a user defined method
System.out.println("Subtraction of two given numbers: "+(x-y));
//display the subtraction of the numbers
}
}
When the above code is executed, it produces the following result
case 1
Enter two numbers for subtraction: 125 475 Difference of two numbers: -350
Case 2
Enter two numbers for subtraction: 550 340 Subtraction of two given numbers: 210
Code to subtract two number in method with return
The program allows to enter two integer values then, it calculates subtraction of the given numbers using return keyword
Program 2
import java.util.Scanner;
public class SubTwoNumbers1{
public static void main(String args[]){
Scanner scan=new Scanner(System.in);
//create a scanner instance for receives input
// from the user - input from keyboard
System.out.print("Enter Two numbers for subtraction: ");
int num1=scan.nextInt();
int num2=scan.nextInt();
//reads the numbers from the user
//input from keyword
int subNum=calcSub(num1,num2);//call the metohd
System.out.println("Subtraction of two given numbers: "+subNum);
}
static int calcSub(int x, int y){ //Define a user defined method
int result=(x-y);
return result;
}
}
When the above code is executed, it produces the following result
case 1
Enter two numbers for subtraction: 1000 500 subtraction of two given numbers: 500
Case 2
Enter two numbers for subtraction: 400 550 subtraction of two given numbers: 150
Code to subtract two floating point numbers
The program allows to enter two float values then, it calculates subtraction of the given numbers
Program 3
import java.util.Scanner;
public class SubTwoNumbers2{
public static void main(String args[]){
Scanner scan=new Scanner(System.in);
//create a scanner instance for receives input
// from the user - input from keyboard
System.out.print("Enter Two numbers for subtraction: ");
double num1=scan.nextDouble();
double num2=scan.nextDouble();
//reads the numbers from the user
//input from keyword
calcSub(num1,num2);//call the metohd
}
static void calcSub(double x, double y){ //Define a user defined method
System.out.println("Subtraction of two numbers: "+(x-y));
//display the sum of the numbers
}
}
When the above code is executed, it produces the following result
Enter two numbers for subtraction: 345.66 34.55 subtraction of two given numbers: 311.11
