You can do more operations like compare,longValue,..more by Using wrapper Integer. == for Integer will not work the rang above -128 and 127. Integer hold cache value upto this range only in memory. More than this range you have to equals() method only to check Integer wrapper class. equals() method will check the value stored in the reference Yes, char is just like any other primitive type, you can just compare them by ==. You can even compare char directly to numbers and use them in calculations eg: public class Test { public static void main (String [] args) { System.out.println ( (int) 'a'); // cast char to int System.out.println ('a' == 97); // char is automatically promoted to Using the equals() method, we create two objects from the main method by giving identical data and comparing the results. This software returns false because the Object class' equals() method only returns true if the references to the objects are identical. Example code for overriding the equals method: EqualsExpl.java 3) String compare by compareTo() method. The above code, demonstrates the use of == operator used for comparing two String objects.. 3) By Using compareTo() method. The String class compareTo() method compares values lexicographically and returns an integer value that describes if first string is less than, equal to or greater than second string. Is there a method similar to equals() that expresses "not equal to"? Java operator "not equal to" help needed. 1. boolean equality operator in If statement. 0. The '==' operator compares memory addresses, ideal for primitive types, while 'equals ()' checks object content, tailor-made for object comparison. Grasping this difference is pivotal for bug-free, efficient code. In Java, the distinction between == and equals () is fundamental yet sometimes overlooked. The == operator checks if two references The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true). If you want to check equality with equals () method in your class equal you have 1. If you're using eclipse (netbeans has similar features, as do most java IDEs), you can simply got to the "Source" menu, and choose "Generate hashcode () and equals ()". Then you select the fields you want to be considered (in your case the list of enum values. That being said, assuming you already have the enum, here's the code that eclipse .
