Java: for(;;) vs. while(true)

Question

What is the difference between a standard while(true) loop and for(;;)?

Is there any, or will both be mapped to the same bytecode after com

Answer 1

It's up to you which one to use. Cause they are equals to compiler.

create file:

// first test
public class Test {
    public static void main(String[] args) {
        while (true) {
            System.out.println("Hi");
        }
    }
}

compile:

javac -g:none Test.java
rename Test.class Test1.class

create file:

// second test
public class Test {
    public static void main(String[] args) {
        for (;;) {
            System.out.println("Hi");
        }
    }
}

compile:

javac -g:none Test.java
mv Test.class Test2.class

compare:

diff -s Test1.class Test2.class
Files Test1.class and Test2.class are identical
