Comparison Operators

Part of the Fundamentals section of Coddy's Java journey — lesson 20 of 73.

Comparison operators are used to compare between two operands.

Sometimes we need to check whether an operand is bigger/smaller/... than another operand.

The following table shows possible operators for comparison:

Operator	Meaning	Example
==	Equal	1 == 2 returns false
!=	Not Equal	1 != 2 returns true
>	Greater Than	1 > 2 returns false
<	Less Than	1 < 2 returns true
>=	Greater or Equal	1 >= 2 returns false
<=	Less or Equal	1 <= 2 returns true

The comparison operator returns true if the comparison is correct or false otherwise.

For example:

int var1 = 13;
int var2 = 12;
boolean var3 = var1 != var2;

var3 will hold true because var1 and var2 are not equal

Remember the boolean type, var3 is a boolean.

Challenge

Beginner

Write a script that initializes 2 variables n1 and n2 with the values 8 and 9 (accordingly).

After that initialize another variable n3 that will hold whether n1 is bigger than n2.

Try it yourself

public class Main {
    public static void main(String[] args) {
        // Type your code below
        
        
        // Don't change the line below
        System.out.println("n1 = " + n1 + ", n2 = " + n2 + ", n3 = " + n3);
    }
}
