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

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

Is there any, or would both be mapped to the same bytecode after compiling?

Semantically, they ' re completely equivalent. It's a matter of taste, but I think while(true) looks cleaner, and are easier to read and understand at first glance. In Java neither of them causes compiler warnings.

At the bytecodelevel, it might depend on the compiler and the level of optimizations, but principle the code Emitted should be the same.

EDIT:

On my compiler, using the bytecode Outline plugin,the bytecode for for(;;){} looks like this:

   L0    LINENUMBER 6 L0   FRAME SAME    GOTO L0

And the bytecode for while(true){} looks like this:

   L0    LINENUMBER 6 L0   FRAME SAME    GOTO L0

So yes, at least for me, they ' re identical.

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

public class Test {    public static void main(String[] args) {        while (true) {            System.out.println("Hi");        }    }}javac -g:none Test.javarename Test.class Test1.classpublic class Test {    public static void main(String[] args) {        for (;;) {            System.out.println("Hi");        }    }}# javac -g:none Test.java# mv Test.class Test2.class# diff -s Test1.class Test2.classFiles Test1.class and Test2.class are identical
