What is Ternary Operator in JAVA
Java ternary operator is the only conditional operator that takes three operands. It is a conditional operator that provides a shorter syntax for the if..else statement. They compile into the equivalent if-else statement, meaning they will be exactly the same.
condition ? trueStatement : falseStatement
- Condition : First part is the condition section.
- trueStatement : Second is the code block which executes in case of first part condition goes true.
- falseStatement : The Third part code block executes if condition results as false.
The following Java program evaluate a condition using if..else statement.
int x = 20, y = 10;
if (x>y)
System.out.println("x is greater than y");
else
System.out.println("x is less than or equal to y");
The same, we can do with ternary operator in java
int x = 20, y = 10;
String result = x > y ? "x is greater than y" : "x is less than or equal to y";
Full Source
public class TestClass {
public static void main(String[] args) {
int x = 20, y = 10;
String result = x > y ? "x is greater than y" : "x is less than or equal to y";
System.out.println(result);
}
}
Output:
x is greater than y
Nested Ternary Operator
You can use Ternary Operator in nested statement like in if..else condition.
Nested if else example
public class TestClass {
public static void main(String[] args) {
int x=10;
int y=20;
int z=30;
if( x > y ) {
if ( x > z ){
System.out.println("x is greatest") ;
}
else{
System.out.println("z is greatest") ;
}
}
else{
if ( y > z ){
System.out.println("y is greatest") ;
}
else{
System.out.println("z is greatest") ;
}
}
}
}
Output
z is greatest
Nested Nested Ternary Operator Example
public class TestClass {
public static void main(String[] args) {
int x=10;
int y=20;
int z=30;
String result = x > y ? x > z ? "x is greatest" : "z is greatest" : y > z ? "y is greatest" : "z is greatest";
System.out.println(result) ;
}
}
Output
z is greatest
