This is how to pass a method to another method in Java 8+.

pass a method to a method.java

// while this is not technically a method, a Runnable is close enough for me.

// this method wants a "method" as an input
void canHazMethod(Runnable methodToRun) {
	// run the method passed in
	methodToRun.run();
}

// this is the method I will use:
Runnable myMethod = () -> {
	System.out.println("my method has been run");
};

// you can see how nice this is compared to Java 7 and earlier:
Runnable anotherMethod = new Runnable() {
	public void run() {
		System.out.println("this is another method to be run");
	}
};

Update: better method of doing this here.
