Not in Java 20

In Java, "not" can be implemented using the ! operator. The ! operator is a unary operator that negates the value of a boolean expression.

Here are some examples of how to use not in Java 20:

1) Simple NOT operation:

boolean a = true;

boolean b = !a;

// b will be false

2) Using NOT to check equality:

int x = 5;

if(!(x == 10)){

    System.out.println("x is not equal to 10");

}

// output: x is not equal to 10

3) Combining NOT with other operators:

int age = 18;

boolean isCitizen = true;

if(!(age >= 18 && isCitizen)){

    System.out.println("You are not eligible to vote");

}

// output: You are not eligible to vote

4) Using NOT with conditional operator:

int num = 11;

String result = (num % 2 == 0) ? "even" : "odd";

String notResult = !(num % 2 == 0) ? "even" : "odd";

System.out.println("Result: " + result);

System.out.println("Not Result: " + notResult);

// output: Result: odd

// Not Result: even
