- System.out.print("I love fishc!");
- System.out.print("I love fishc!");
- System.out.print("pi = " + 3.14);
- }

格式化输出
语法跟 C 很像(可以参考) -> https://fishc.com.cn/forum.php?mod=viewthread&tid=66471
1. printf
- public class Book
- {
- public static void main(String args[])
- {
- System.out.printf("pi = %.2f\n", 3.14);
- System.out.printf("I love %s!\n", "fishc");
- System.out.printf("%d %c %d = %d\n", 1, '+', 1, 2);
- }
- }
复制代码
效果:
- pi = 3.14
- I love fishc!
- 1 + 1 = 2
复制代码
2. format
- public class Book
- {
- public static void main(String args[])
- {
- System.out.format("pi = %.2f\n", 3.14);
- System.out.format("I love %s!\n", "fishc");
- System.out.format("%d %c %d = %d\n", 1, '+', 1, 2);
- }
- }
