Course Introduction:Double is one of the primitive data types available in Java to represent decimal point numbers. It belongs to the floating point type, also known as real number, and is used when calculations require decimal values. For example, to express the result of 1/5, which is 0.2, the results of sine and cosine also need a decimal point. In addition to the representation of decimal values, we can also perform comparison operations between two double-type variables. This article aims to explore possible ways of comparing two variables with the help of example programs. Comparing Doubles in Java In this section, we will explain how to compare Doubles in Java. We can use the following methods - Using == operator Using compareTo() method Using compare() method Let us discuss them one by one with a sample program.
