Every Java primitive data type has a class dedicated to it. These classes wrap the primitive data type into an object of that class. Therefore, it is known as wrapper classes.The following is the program that displays a Primitive DataType in a Wrapper Object.Example Live Demopublic class Demo {    public ... Read More

To parse and format to hexadecimal in Java, we have used the BigInteger class. The java.math.BigInteger class provides operations analogues to all of Java's primitive integer operators and for all relevant methods from java.lang.Math.In the below example, we have taken BigInteger and created an object. With that, some values have ... Read More
