Three-way operator | Ternary operator in Java

The one and only conditional operator that accepts three operands is the three-way operator in Java. Java programmers frequently use it as a one-line alternative to the if-then-else expression. The ternary operator can be used in place of if-else statements, and it can even be used to create switch statements with nested ternary operators. The conditional operator uses less space and aids in writing if-else statements as quickly as possible even if it adheres to the same algorithm as an if-else statement.

Syntax:

If operates similarly to an if-else statement in that Expression2 is performed if Expression1 seems to be true and Expression3 is then executed in the event that Expression1 is false.

if(Expression1) // checking if expression 1 is true
{
    variable = Expression2; // if expression 1 is true then expression 2 is assigned
}
else
{
    variable = Expression3; // else expression 3 is assigned
}

Example:

n1 = 1;n2 = 2;result = (n1>n2) ? (n1*n2):(n1+n2)Since n1<n2, the second operation gets performed. That is,result = n1+n2 = 3The output will be 3.

Example 1:

ThreewayOperatorExpl.java

// Java program to find the largest among two
// numbers using three way  operator
 
import java.io.*;
 
class ThreewayOperatorExpl {
    public static void main(String args[])
    {
 
        // Declaring the variables
        int a = 5, b = 10, maximum;
 
        System.out.println(" The First number is: " + a);
        System.out.println(" The Second number is: " + b);
 
        // checking for the largest number among a and b
        maximum = (a > b) ? a : b;
 
        // Printing the largest number among a and b
        System.out.println(" The Maximum number is = " + maximum);
    }
}

Output:

Three-way operator | Ternary operator in Java

Time Complexity is: O(1)

Auxiliary Space is: O(1)

Example 2:

ThreewayOperatorExpl1.java

// Java code to illustrate three way operator
 
import java.io.*;
 
class ThreewayOperatorExpl1 {
    public static void main(String args[])
    {
 
        // declaring the variables
        int a = 51, b = 10, result;
 
        System.out.println(" The First number is: " + a);
        System.out.println(" The Second number is: " + b);
 
        // Using three way operator
        result = (a > b) ? (a + b) : (a - b);
 
        // Printing the result after performing three way operator
        System.out.println("  The Result is = " + result);
    }
}

Output:
