Metadata

ID: java-code-style/for-loop-should-be-while-loop

Language: Java

Severity: Notice

Category: Code Style

Description

This rule identifies instances where simplifying for loops is possible which can make these loops more concise.

Non-Compliant Code Examples

// No init or update nodes; can be rewritten `while (condition)`
public class Foo {
    void bar() {
        for(;true;) true;

        for(; true ;){
        	System.out.println("bar");
        }
        
        for(; i < 42 ;) true;
        
        for(;;);
    }
}

Compliant Code Examples

public class Foo {
    void bar() {
        for(int i = 0; i < 42; i++);
    }
}
