Java Strings

A String is an object that represents a sequence of characters.
For example, “HelloWorld” is a string of 10 characters.
For example:

String s = "HelloTech";

The + (plus) operator between strings adds them together to make a new string. This process is called concatenation.The resulted string is the first string put together with the second string.For example:

String firstName, lastName;
firstName = "sani";
lastName = "kamal";
System.out.println("My name is " + firstName +" "+lastName);
 
// Prints: My name is sani kamal
The char data type represents a single character.
