check if two variable is not equal in java

if (variable1 != variable2) {
  System.out.println("The two values are not equal");
}

This code checks if two variables (variable1 and variable2) are not equal. If they are not equal, it prints out a message that says “The two values are not equal”. This is done by using an if statement to compare the two values and check that they are not equal. If they are not equal, then the code inside the if statement will execute, in this case the code that prints out the message. If the two values are equal, then nothing will happen because the code inside the if statement will not execute. This code is useful for comparing values in programming to determine if something should happen or not.
