Java String 输出格式

HDU 2093:

System.out.format("%-10s %2d %4d\n", p[i].name, p[i].a, p[i].b); //错误

System.out.println(String.format("%-10s %2d %4d", p[i].name, p[i].a, p[i].b));// 正确

例子：

System.out.println(String.format("%1$,09d", -3123));
System.out.println(String.format("%1$9d", -31));
System.out.println(String.format("%1$-9d", -31));
System.out.println(String.format("%1$(9d", -31));
System.out.println(String.format("%1$#9x", 5689));


System.out.println(String.format("%1$c", 'A'));

System.out.println(String.format("%1$8c", 'A')); //前面留7个空格

System.out.println(String.format("%1$-8c", 'A')); //后面留7个空格

String str = "abcd";
System.out.println(String.format("%1$-10s", str) + "123");
System.out.println(String.format("%1$10s", str) + "123");

int n = 16;
System.out.format("%03x\n", n);

结果：

-0003,123
　　-31
-31
(31)
0x1639
A
　　A
A　　
abcd 123
　　abcd123
