If else statement using one line.

Question:

How to write this if else statement in 1 line?

    if(i1==i2){
      b1 = true;
    } else {
      b1 = false;
    }

Answer:

Using the ternary operator.

  result = condition ? value1 : value2; 

Code:

public class Example {
  public static void main(String args[]){
 
    int i1=0;
    int i2=1;
    boolean b1;
    boolean b2;
 
    if(i1==i2){
      b1 = true;
    } else {
      b1 = false;
    }
    System.out.println("b1:" + b1);
 
    // one liner 
    b2= ( (i1==i2) ? true : false );
    System.out.println("b2:" + b2);
 
  }
}

Output:

$ java Example
b1:false
b2:false
