java-字符串问题

String [][] strs = {
				{"java","java","java"},
				{"java","java"}
		};
		System.out.println(strs.length);
		System.out.println(strs[0].length);
		System.out.println(strs[1].length);
		System.out.println(strs[0][0]==strs[0][1]);
		System.out.println(strs[1][0]==strs[0][1]);

结果是：

2
3
2
true
true
