java if statement source code-Simple Java Programs

In this video I have shown the four common different if statements with example source code.
The four if statements are,
1. if statement
2. if-else statement
3. if-else-if ladder
4 .nested if statement

1. Project Structure

2. If_Statement.java

   
   package com.chillyfacts.com;
   public class If_Statement {
   	public static void main(String[] args) {
   		int i=15;
   		System.out.println(i>10);
   		if(i>10){
   			System.out.println("i is greater than 10");
   		}
   	}
   }
   

   Output

   true
   i is greater than 10
   

3. If_Else_Statement.java

   
   package com.chillyfacts.com;
   public class If_Else_Statement {
   	public static void main(String[] args) {
   		int i=15;
   		System.out.println(i>10);
   		if(i>10){
   			System.out.println("i is greater than 10");
   		}else{
   			System.out.println("i is less than 10");
   		}
   	}
   }
   

   Output

   true
   i is greater than 10
   

4. If_Else_If_Statement.java

   
   package com.chillyfacts.com;
   public class If_Else_If_Statement {
   	public static void main(String[] args) {
   		int i=60;		
   		if(i<5){
   			System.out.println("i is less than 5");
   		}else if(i<10){
   			System.out.println("i is less than 10");
   		}else{
   			System.out.println("i is greater than 10");
   		}		
   	}
   }
   

   output

   i is greater than 10
   

5. Nested_If_Statement

   
   package com.chillyfacts.com;
   public class Nested_If_Statement {
   	public static void main(String[] args) {
   		int i=16;
   		//System.out.println(i>10);
   		if(i<5){
   			System.out.println("i is less than 5");
   		}else if(i<10){
   			System.out.println("i is less than 10");
   		}else if(i<15){
   			System.out.println("i is less than 15");
   		}else if(i<20){
   			System.out.println("i is less than 20");
   		}else if(i<25){
   			System.out.println("i is less than 25");
   		}else{
   			System.out.println("i is greater than 25");
   		}
   		System.out.println("Done");
   	}
   }

Output

i is less than 20
Done
