STRINGS

Strings are inseparable part of computer programming. Hence, Java has provided an inbuilt class String to handle strings. In C/C++, strings are stored in array of characters terminated by null character. In Java, we need not worry about how it is implemented internally.

10.1 Introduction

Java has a class String defined in the package java.lang. We are given a rich set of methods to work with strings. Table 10.1 lists the important methods for our ready reference.
