12/23/2023 0 Comments Java does not equal signSo, in our cases, we check if the str1.equals(str2) throws true, and if yes, we use the operator, which proves that the variables are not the same. The ! operator makes the result opposite, which means if the str1.equals(str2) statement returns true as a result, the operator ! makes it false. In the if condition, we check the str1.equals(str2) with a ! operator at the beginning. ![]() In the example, we take two String variables. We can use the ! operator with the equals() method to check if the contents of the variables match or not. ![]() Using the Not Equals Operator With equals() The true block of the if condition executes when the condition is not met (when num1 is not equal to num2), and if they match, then the false block is executed.Īs both the variables have different values, the true block of the condition executes. The variable is on the right side of the operator. Notice that ONE equal sign is used to assign a value, but TWO equal signs are used to check to see if numerical values are equal to one another. In the condition, write num1 != num2 where the variable on the left side of the operator is compared. Not Equal operator takes two operands: left operand and right operand as shown in the following. We create an if condition to check if the variables match or not. The symbols used for Not Equal operator is. ![]() Here, num1 contains the value 123, and the num2 variable has 321. The program has two int variables, num1 and num2. The most basic way to use the not equals operator is to check for equality between two variables. The Relational Operators (not equal to), Checks if the values of two operands are equal or not, if values are not equal then condition becomes true. We can also use ! with the equals() method to check the non-equality of the data. ApTo say does not equal in Java, put an exclamation mark in front of equals sign like so. This article shows how to use the != operator that we also call the not equals operator. To say does not equal in Java, put an exclamation mark in front of equals sign like so.
