If-else Satament in Java

                                             If-Statement mainly used to test the condition in this case it returns true or false .Let's Assume a situation where you have been asked or said to execute a statement there may be a condition should be true or false. Let suppose you have done something wrong then your father will be ask  that have you done this or not you may return true or false .If retun true then you may be get slapped else some other good thing can be happen also with you.So apart from above there are some different type if-else statement are as following

1. if Statement

1. if-else Statement

1. if-else-if Ladder

1. nested if statement

 If Statement  in Java

1. If  Statement: -  Java  if condition check condition if  condition returns true then execute code under if block or if  condition returns false then exit.

Syntax

if(condition){ 

 //code to be executed 

}
in the above said syntax you can easily see how the condition written in if and statement in if block will execute after check if condition.

Let's See an example on on if Statement&nbsp

public class IfExampleinJava {
   
    public static void main(String[] args) {  
    //defining an 'value' variable  
    int value=90;  
    //checking the value  
    if(value<100){  
        System.out.print("Oh no Century missed");  
    }  
}
    
}

output: Oh no Century missed

2. if-else Statement: - In above there was only if condition mean there was no statement in the case if condition returns false but in the if -else statement we hase an alternate if codition return we can execute some in the case else condition return false still we can execute some block of code let see the syntax

Flow Chart of  if-else Statement

Syntax

if(condition)
  { 
   //code if condition is true 
 }else
     { 
 //code if condition is false 
 }

lets See an Example on if-Else Statement


public class IfExampleinJava {
   
    public static void main(String[] args) {  
    //defining an 'value' variable  
    int value=90;  
    //checking the value  
    if(value>=100){  
        System.out.print("Century");  
    }else{
        System.out.print("it's Half Century ");  
    } 
}
    
}

Output:  it's Half Century
