Java Code Viewer

What it does

The viewer inserts a newline and one indent after each {, a newline after each ;, and a newline before each }, then collapses the blank lines that creates. It does not parse Java, track nesting depth, or understand package, import, or class structure, so every brace level is indented the same single step.

Worked example

Input:

public class Main { public static void main(String[] args) { System.out.println("Hello"); } }

Output:

public class Main {
  public static void main(String[] args) {
  System.out.println("Hello");
}
}

Java-specific notes

• The semicolons in a classic for (int i = 0; i < n; i++) header are broken onto separate lines, so for-loops need a manual rejoin.
• Array initializers {1, 2, 3}, annotations such as @Override, lambdas x -> x + 1, and text blocks """...""" pass through, but braces inside them are still split.
• Generic types such as List<Map<String, Integer>> are left untouched.

When to use it

Turning a single pasted class or method from an email, a forum answer, or a stack trace into something scannable, or spotting an unbalanced block quickly. For project formatting use your IDE, google-java-format, or a Spotless / Checkstyle setup that actually parses the language.
