Ternary operator in Java
The ternary operator is a simple conditional branching statement. It returns a value based on condition.
int num = 54;
String str = num > 100 ? "big number" : "small number";num > 100 ? is our condition.
"big number" the first value(before :) will be returned if a condition is true.
"small number" the second value(after :) will be returned if a condition is false. In our case, this value is returned because the condition is false.
Turnery operator can be used with any other data types as well.
public class Main {
public static void main(String[] args) {
boolean b = false;
int num = b ? 7 : 9;
System.out.println(num); // 9
}
}public class Main {
public static void main(String[] args) {
double score = 75.0;
char grade = score >= 50&& score <= 100 ? 'A' : 'F';
System.out.println(grade); // A
}
}public class Main {
public static void main(String[] args) {
int num = 1 > 2 ? 7 : 9 > 3 ? 0 : 3;
System.out.println(num); // 0
}
}
