Java syntax and structure can be a little intimidating if you are just getting started. But as you learn the language, you'll see that code formatting is crucial for enhancing readability, maintainability and teamwork. A Java Code Formatter & Beautifier becomes a crucial tool in this situation.
If you’re also working with JavaScript or Python, try our JavaScript Formatter or Python Formatter to keep your code clean across languages.
What is a Java Code Formatter?
An application that automatically formats Java source code in accordance with a predetermined set of style guidelines is called a Java Code Formatter. Also, it modifies alignment, line breaks, indentation and spaces to guarantee that your code has a clear - consistent structure.
Although it is advantageous to make code look good, a formatter real strength is in creating a coding environment where developers can flourish. Developers can concentrate on logic, and problem solving, and functionality instead of becoming bogged down in figuring out inconsistent formatting styles when their codebase is well formatted.
What Makes a Java Code Beautifier Useful?
Several developers work together to create software, contributing to the same codebase. The placement of braces, line breaks, spacing and indentation may vary from developer to developer. A disjointed and challenging to read codebase may result from this variety in coding styles.
By removing inconsistencies and substituting a neat, standardized format, a Java beautifier ensures consistency throughout the entire codebase. As a result, the code is easier to read, collaboration is improved, and onboarding new team members is made simpler.
Unformatted Java code might look like this:
public class Main{public static void main(String[] args){System.out.println("Hello World");for(int i=0;i<\10;i++){if(i%2==0){System.out.println(i);}}}}
What Can You Do with This Java Tool?
This tool can help you with the following:
Format Java Code- Upload .java files or paste Java code.
- Choose your desired code style.
- To improve the appearance of your code click "Format".
- Check the prepared output for syntax highlighting.
- Download or copy the completed code.
Sample Java Code for Testing
// Unformatted Java Code
public class Calculator{private double result;public Calculator(){result=0;}public void add(double x){result+=x;}public void subtract(double x){result-=x;}public double getResult(){return result;}public static void main(String[] args){Calculator calc=new Calculator();calc.add(5.2);calc.subtract(1.7);System.out.println("Result: "+calc.getResult());}}
// Formatted Result (Google Java Style):
public class Calculator {
private double result;
public Calculator() {
result = 0;
}
public void add(double x) {
result += x;
}
public void subtract(double x) {
result -= x;
}
public double getResult() {
return result;
}
public static void main(String[] args) {
Calculator calc = new Calculator();
calc.add(5.2);
calc.subtract(1.7);
System.out.println("Result: " + calc.getResult());
}
