To compare objects in Java, check the properties or the hash value of given objects. If the properties of both objects matches, then they are equal. If either property is different, it indicate that the objects are not equal. NOTE: Don't use equality operator (==) to compare objects as it ... Read More

For a given a string, write a Java program to find the frequency of a particular character. In Java, String is a datatype that contains one or more characters and is enclosed in double quotes(“ ”). Finding Frequency of a Character in a String To find the Frequency ... Read More

String interpolation is a concatenation technique used to display output text dynamically or effectively by replacing the placeholder characters with variables (or strings in the subsequent examples). It restructures the code and prevents the need to repeatedly use variables to produce the output. It makes it efficient to write ... Read More

Any whole number which is greater than 1 and has only two factors i.e. 1 and the number itself, is called a prime number. Other than these two number it has no positive divisor. In this article, we will explain Java programs to print prime numbers between 1 to 100. ... Read More

The strictfp keyword is a modifier that stands for strict floating point. As the name suggests, it ensures that floating-point operations give the same result on any platform. This keyword was introduced in Java version 1.2. In Java, the floating point precision may vary from one platform to another. The ... Read More

Array is the common way to store similar types of items together in Java. The stored items or values are referred as elements of the array. In this article, we are going to learn how to create an array and print its elements. Printing elements of an array in Java ... Read More

Given an array of type Integer, write a Java program to find the odd and even numbers from that array. Those numbers which are completely divisible by 2 are called even numbers and if a number gives 1 as a remainder on dividing with 2 is known as odd number. ... Read More

Let's say, we have a numeric value of type double and our task is to convert it into other numeric primitive data types. To perform this operation, we require explicit casting as double is the largest primitive datatype available in Java. The process of converting larger data type into smaller ... Read More

Given a sentence (string), let's say str, count the total number of vowels in it. In Java, the String is a non-primitive data type which is used to define sequence of characters. And, the English letters a, e, i, o, and u are known as vowels. To count the number ... Read More

A running total (also known as an accumulated total) of a list represents the sum of a sequence of elements. As new elements are added to the sequence, the running total continuously updates. To perform this operation in Java, we can use for loop and while loop in our program. ... Read More
