Introduction Before learning about JVM it is important to know about JDK (Java Development Kit) and JRE (Java Runtime Environment). Below figure […]
This article explains about handling strings in Java programs. It is common in Java programs to work with strings to solve different problems. So, let’s see how to work with strings in Java. Introduction to Strings A string is a collection of characters. In Java, strings can be created using three predefined classes […]
In this article we will learn how to declare and use strings in our Java programs with appropriate sample code examples. Like in any programming language, a string is a collection of characters.
