Question

我如何制作我的代码

class Factorial {
    public static void main(String args[]) {
        int n, c, fact = 1;  

        for ( c = 1 ; c <= 5 ; c++ ) {
            fact = fact*c;
            System.out.println(fact);
        }
    }
}

看起来像这样

Answer 1

System.out.println(c+" "+fact);

Answer 2

您可以使用以下代码。

您可以让System.out.println（）在新行上打印它和System.out.print（）在同一行上打印东西。

class Factorial {
    public static void main(String args[]) {
        int n, c, fact = 1;  

        System.out.println("x x!");
        for ( c = 1 ; c <= 5 ; c++ ) {
            fact = fact*c;
            System.out.println(c + " " +fact);
        }
    }
}

Answer 3

又一个解决方案：

private static final String TEMPLATE = "%s %s";

public static void main(String args[]) {
    int n, c, fact = 1;
    System.out.println(String.format(TEMPLATE, "X", "X!"));
    for ( c = 1 ; c <= 5 ; c++ ) {
        fact = fact*c;
        System.out.println(String.format(TEMPLATE, c, fact));
    }
}

Answer 4

试试这个：

  public static void main(String args[]) {
    int n, c, fact = 1;


    System.out.println("X X! ");
    for (c = 1; c <= 5; c++) {
        fact = fact * c;

        System.out.println(c + " " + fact);
    }

Answer 5

System.out.println(c+" "+fact);

Answer 6

试

for ( c = 1 ; c <= 5 ; c++ ) {
            fact = fact*c;
            System.out.println(c + " " +fact);
        }

Answer 7

class Factorial {
    public static void main(String args[]) {
        int n, c, fact = 1;
        for ( c = 1 ; c <= 5 ; c++ ) {
            fact = fact*c;
            System.out.print(c+"! = "+fact+(c==5?".":", "));
        }
    }
}

Answer 8

不确定您是在询问是否在一行中格式化输出，或者您想要进行一些逻辑更改：

为了格式化一行中的输出，这里是更新的代码：

       public class Factorial {
       public static void main(String args[]) {
            int n, c, fact = 1;  

            for ( c = 1 ; c <= 5 ; c++ ) {
                fact = fact*c;
                System.out.print(fact);
                System.out.print(" ");
            }
        }
}
