Java Print Variables

Java Print Variables

In Java, you can print variables using different methods like print(), println(), and printf(). Printing variables helps display stored values on the screen.

Printing Variables Using `println()`

Printing Text + Variables Together

Use the + operator (concatenation):

Output:

Printing Multiple Variables in One Statement

Output:

Printing Numbers in Expressions

Java will perform mathematical operations first if parentheses are not used carefully.

Output:

Printing Variables Using `print()`

Output:

Printing Variables Using `printf()` (Formatted Output)

Output:

Common Format Specifiers:

Format Code	Meaning
`%d`	Integer
`%f`	Floating-point number
`%.2f`	Floating number with 2 decimals
`%s`	String
`%c`	Character

Example Program

class PrintVariables {
public static void main(String[] args) {String firstName = "John";
int age = 25;
double salary = 50000.75;

System.out.println("Name: " + firstName);
System.out.println("Age: " + age);
System.out.println("Salary: " + salary);

System.out.printf("Formatted Salary: %.2f", salary);
}
}

class PrintVariables {

public static void main(String[] args) {String firstName = "John";

int age = 25;

double salary = 50000.75;

System.out.println("Name: " + firstName);

System.out.println("Age: " + age);

System.out.println("Salary: " + salary);

System.out.printf("Formatted Salary: %.2f", salary);

}

Summary

Method	Use
`println()`	Prints variable + moves to new line
`print()`	Prints without new line
`printf()`	Prints formatted values
