String Data Type

Introduction

The char type represents only one character. To represent a string of characters, use the data type called String.

Example:

String message = "Welcome to Java";

String is actually a predefined class in the Java library just like the System class. The String type is not a primitive type. It is known as a references type.

Concatenating Strings

Strings are more commonly concatenated with the + operator.

Example:

String message = "Welcome " + "to " + "Java";

The value of message will be Welcome to Java.

Exercise:

What is the value of s and s1 in the following statements?

String s = "Chapter" + 2;

String s1 = "Supplement" + 'B';
