java 遍历String数组的值比较

String[] strs={"a","b","c","d","a"};
			System.out.println(strs.length);
	        for (int i = 0; i < strs.length; i++) {
	            for (int j = i+1; j < strs.length; j++) {
	            	System.out.print(strs[i]+"=="+strs[j]+"-----");
	                if(strs[i].equals(strs[j])){
	                	System.out.println(true);
	                	break;
	                }else{
	                	System.out.println(false);
	                }
	            }
	        }
