public class Test{
public static void main(String[] args)
{ System.out.println("1\t"+"2\t"+"6\t"+"7"); System.out.println("3\t"+"5\t"+"8\t"+"13");
System.out.println("4\t"+"9\t"+"12\t"+"14"); System.out.println("10\t"+"11\t"+"15\t"+"16");
}}这是最简单的了

不要求算法 只要输出就可以吗？ 答案补充 public class Test
{
public static void main(String[] args)
{
System.out.println("1\t"+"2\t"+"6\t"+"7");
System.out.println("3\t"+"5\t"+"8\t"+"13");
System.out.println("4\t"+"9\t"+"12\t"+"14");
System.out.println("10\t"+"11\t"+"15\t"+"16");
}
}
