Java: Infinite Loop Convention [closed]

Question

What is the convention for an infinite loop in Java? Should I write while(true) or for(;;)? I personally would use while(true) because I use while loops less often.

Answer 1

There is no difference in bytecode between while(true) and for(;;) but I prefer while(true) since it is less confusing (especially for someone new to Java).

You can check it with this code example

void test1(){     for (;;){         System.out.println("hello");     } } void test2(){     while(true){         System.out.println("world");     } } 

When you use command javap -c ClassWithThoseMethods you will get

  void test1();     Code:        0: getstatic     #15                 // Field java/lang/System.out:Ljava/io/PrintStream;        3: ldc           #21                 // String hello        5: invokevirtual #23                 // Method java/io/PrintStream.println:(Ljava/lang/String;)V        8: goto          0    void test2();     Code:        0: getstatic     #15                 // Field java/lang/System.out:Ljava/io/PrintStream;        3: ldc           #31                 // String world        5: invokevirtual #23                 // Method java/io/PrintStream.println:(Ljava/lang/String;)V        8: goto          0 

which shows same structure (except "hello" vs "world" strings) .

Answer 2

I prefer while(true), because I use while loops less often than for loops. For loops have better uses and while(true) is much cleaner and easy to read than for(;;)
