Ternary operator is equivalent to if-else statement If this logical expression execution result is true then only the block associated with if statement will execute otherwise control will reach to else block.

		int age =25;

		String ageCategory=age<18? "Minor" : "Adult";
		System.out.println("Category for Age :" + age +" is"+ ageCategory );

		//Odd even test
		int number=50;
		boolean isEven= number%2==0 ? true: false;

		System.out.println("Number :" + 50 +" is even "+ isEven );
	}

}

Output

Category for Age :25 isAdult
Number :50 is even true
