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()`

Output:

📌 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
