Code For if-else Statement

In this example, We will discuss about the use and implementation of the if-else statement in the java programs. The if-else statement is a decision making statement , If the Boolean expression evaluates true value then if block executed otherwise the else block is executed.

The syntax for if-else statement is as-

if(Boolean-Expression){
		   //Executes if Boolean expression is true
		     }
	else{
		   //Executes if Boolean expression is false
		}

In the given example, We get the input an integer value at run time and checks it to be a positive number or not as folowing.

Example: IfElseExample.java

package com.devmanuals2;

import java.io.*;

public class IfElseExample {

	public static void main(String[] args) throws IOException {
		BufferedReader buffread = new BufferedReader(new InputStreamReader(
				System.in));

		System.out.println("Enter integer number");
		String str = buffread.readLine();
		int number = Integer.parseInt(str);

		if (number < 0) {
			System.out.println("The number " + number + " is negative");
		} else {
			System.out.println("The number " + number + " is positive");
		}

	}

}
