Answer 1

Amruta use it like this:
public class Program
{
public static void main(String[] args)
{
System.out.println((10>9)?"10>9":"10<9");
}
}
Ternary operator has return type so its must return a value from ans either one of them.......
Your function works on void method i.e print directly and it doesn't support void invocation inside it so it shows error....
Well I too didn't know that much.....so sorry😅
Hope this helps.....😊

Answer 2

Amruta
They are ternary/conditional operators, not conditional statements
● U can replace them by if-else conditional statements in above code to make that work.

Ketan
U can remove 1 more bracket in condition 10>9, that will also work ☺

Answer 3

Ketan It works perfect
But why its not working when using printing statements in ternary statement?

Canche Emmanuel , Gaurav Agrawal thanks for help

Answer 5

Ketan thanks for help

Answer 6

Ron Alvarez Yes I know that but I wanted to know the reason behind the error

Answer 7

System.out.println((10>9)?"10>9":"10<9");
Here you may put a string or a variable.

I should do it this way:

result = (10>9)?"10>9":"10<9" ;
System.out.println(result)

Answer 8

It is a compile-time error for either operand expression to be an invocation of a void method and System.out.println is void (does not return any value).

Answer 10

System.out.println((10>9)?"10>9":"10<9"); Here you may put a string or a variable. I should do it this way: result = (10>9)?"10>9":"10<9" ; System.out.println(result)

Answer 11

public class Program
{
public static void main(String[] args) {
/*here you can declare 2 variables for 10 & 9 values*/
if (10>9)
{
System.out.println("10>9");
}
else
{
System.out.println("10<9");
}
}
}
/*I think! in java it should be like that😊*/

Answer 12

The ternary operator should always provide as a value. If you are going to make statements using ternaries you will get errors. So the ternary operator should go inside the println() method.

Answer 13

S1s yes its will work for ternary😀

Answer 14

I did it this way...is it okay for you...?

public class Program
{
public static void main(String[] args) {
int a=9;
int b=10;

System.out.println("10>9?");

if(10>9)

{ System.out.println("10>9");
}
else{
System.out.println("10<9");
}
}
}

Answer 15

u can use if/else for better understanding

Answer 16

It seems that kind of code is not used in Java...but if you try to do it that way it becomes more complicated

Answer 17

S1s your code above runs perfectly

Answer 18

good great
