System.our.println((c^d)+"通過");?

換成

System.out.println((c^d)+"通過");?

試一試吧

public?class?HelloWorld?{
????public?static?void?main(String[]?args)?{		
????boolean?a?=?true;?//?a同意		
????boolean?b?=?false;?//?b反對(duì)		
????boolean?c?=?false;?//?c反對(duì)		
????boolean?d?=?true;?//?d同意	?????
????System.out.println((a?&&?b)+"未通過");	?????
????System.out.println((a?||?d)+"通過");	?????
????System.out.println((!a)+"未通過");	?????
????System.our.println((c^d)+"通過");????????????????	
????}
