Java条件短路操作

@Test
	void test() {
		boolean boolean1 = shortCircuit1 () && shortCircuit2 ();
		boolean boolean2 = shortCircuit2 () && shortCircuit1 ();
		System.out.println();
		boolean boolean3 = shortCircuit1 () || shortCircuit2 ();
		boolean boolean4 = shortCircuit2 () || shortCircuit1 ();
		
	}

	boolean shortCircuit1 () {
		System.out.println("短路1");
		return true;
	}
	
	boolean shortCircuit2 () {
		System.out.println("短路2");
		return false;
	}

 输出结果:

短路1

短路2

短路2

 

短路1

短路2

短路1

 

请分析一下为什么会这样.
