Print Week Example in Java

Introduction

Print Week is a classic Java console program that demonstrates the concept with complete source code and sample output. Practical numeric and utility programs — primes, factorial, palindrome and similar classics.

This tutorial walks through the program line by line, explains how the logic works, and highlights best practices you can apply in your own code.

Syntax

Variable_name=Calendar.WEEK_OF_MONTH
Variable_name=Calendar.WEEK_OF_YEAR

Print Week Example Program

import java.util.Calendar;
 
public class PrintWeek {
	public static void main(String[] args) {
		Calendar c = Calendar.getInstance();
		System.out.println("Current week of month is : " +c.get(Calendar.WEEK_OF_MONTH));
		System.out.println("Current week of year is : " +c.get(Calendar.WEEK_OF_YEAR));
	}
}

Sample Output

Current week of month is : 2
Current week of year is : 19

When to use

Use this print week example when learning or revising core Java syntax.

How it works

1. Execution begins in the main method — the JVM calls this method when you run the class.

2. import java.util.Calendar; imports a class used later in the program.

3. Calendar c = Calendar.getInstance(); updates a variable used in the calculation or output.

4. A println / print call writes text to the console — part of the sample output below.

5. A println / print call writes text to the console — part of the sample output below.

6. Compare your console output with the sample output for Print Week to confirm the program behaves correctly.

Best Practices

• Use meaningful variable and class names that describe their purpose.
• Compile and run the program locally — modify values to see how output changes.
• Read compiler errors carefully; they usually point to the exact line to fix.

Common Mistakes

• Copying code without understanding each line — practice by changing one statement at a time.
• Mismatching the public class name and the .java filename.
• Forgetting semicolons at the end of statements.
