Java Characters

Characters

The char data type is designed to store a single character, and the character should be enclosed in single quotes.

Example:

char grade = 'A';
System.out.println(grade); // Outputs: A

char grade = 'A';

System.out.println(grade); // Outputs: A

You can also use ASCII values to represent characters. ASCII values are numerical codes for characters.

Example:

In this example, 65, 66, and 67 are the ASCII values for ‘A’, ‘B’, and ‘C’, respectively.

char firstLetter = 65, secondLetter = 66, thirdLetter = 67;
System.out.println(firstLetter); // Outputs: A
System.out.println(secondLetter); // Outputs: B
System.out.println(thirdLetter); // Outputs: C

char firstLetter = 65, secondLetter = 66, thirdLetter = 67;

System.out.println(firstLetter); // Outputs: A

System.out.println(secondLetter); // Outputs: B

System.out.println(thirdLetter); // Outputs: C

Strings

The String data type is used to store a series of characters, and it must be enclosed in double quotes.

Example:

Strings are not considered primitive data types; they are objects with methods that provide various functionalities.

String greeting = "Hello World";
System.out.println(greeting); // Outputs: Hello World

String greeting = "Hello World";

System.out.println(greeting); // Outputs: Hello World

Summary

• Characters (char): Used for storing a single character and enclosed in single quotes.
• Strings (String): Used for storing sequences of characters and enclosed in double quotes.
• ASCII Values: Can be used to represent characters by their numerical codes.
