Strings - Introduction

Introduction: –

Strings are called character array. i.e. sequence of characters.

This is a class that is defined in java.lang package.

Always Remember it is not a data type.

This is one of the most important topics from which questions are asked in interviews.

String string_name = “put your content inside double quotes”;

Example:

String s = “Ravi”;

If you will use char then use a single quote and for string use double-quotes.

String class has many inbuilt methods. Let’s explore them –

The string class has a length() method for this.

String s = “Ravi”;
s.length(); // it will return the length of string.

They have inbuilt methods like touppercase, tolowercase .. etc.

in the next post, I will tell you how to convert from int to string and vice versa.
