While it is technically correct to use a ``++Thread++`` where a ``++Runnable++`` is called for, the semantics of the two objects are different, and mixing them is a bad practice that will likely lead to headaches in the future.


The crux of the issue is that ``++Thread++`` is a larger concept than ``++Runnable++``. A ``++Runnable++`` is an object whose running should be managed. A ``++Thread++`` expects to manage the running of itself or other ``++Runnables++``. 


== Noncompliant Code Example

[source,java]
----
	public static void main(String[] args) {
		Thread r =new Thread() {
			int p;
			@Override
			public void run() {
				while(true)
					System.out.println("a");
			}
		};
		new Thread(r).start();  // Noncompliant
----


== Compliant Solution

[source,java]
----
	public static void main(String[] args) {
		Runnable r =new Runnable() {
			int p;
			@Override
			public void run() {
				while(true)
					System.out.println("a");
			}
		};
		new Thread(r).start();
