Returns a value less than 0,0,value greater than 0 for less than,equal to and greater than. It's useful for storing numbers that outgrow the integer data type. Here, we are going to learn how to convert long primitive type into int and Long object into int. Example : On the other hand, double stores values from 1.7e-308 to 1.7e+038. The java.util.Arrays.copyOfRange() method is used to copy the specified range of the specified array into a new array. This should be used when comparing two Long values for numerical equality as it would differentiate between less and greater values. We can convert long to int in java using typecasting. Attention reader! Difficulty Level : Easy. Don’t stop learning now. In the second line, the num_b is declared and a value is assigned at the time of declaration. Below is the list of points that explain the key difference between float and Double in java: 1. The variable is declared inside the loop and used with an array for displaying the array elements. There are certain scenarios when you need working with objects rather than using primitive data types for storing numeric values; I will explain this in the later part of this tutorial. public class Range extends Object implements Serializable. It is an inbuilt function which converts the value of BigInteger to a long and checks for lost information. A range is defined to contain all the values between the minimum and maximum values, where the minimum/maximum value can be considered either included or excluded from the range.
