我有一個任務來創建一個程序,提示用戶輸入一個整數,然後根據用戶輸入使用while循環創建一個乘法表。Java - 在一行中輸出用戶輸入整數的整數
輸出乘法表必須包含標題行和列。我堅持的是如何創建標題行,因爲標題必須計算的數字取決於用戶輸入。
我在while循環中創建了標題列,該循環對行進行格式化,因爲每次循環逐步完成時都會創建一個新行。但標題行只打印一次,因此我不能使用格式化列創建它的while循環。
如何創建標題行,以便將用戶輸入遞減爲1,並輸出來自1,2,3,...用戶輸入的所有整數值?
這是我有:
import java.util.Scanner;
public class Multiplication
{
public static void main(String[] args)
{
int number;
String yesno = "Y";
Scanner keyboard = new Scanner(System.in);
System.out.print ("This program generates a multiplication table ");
System.out.println("based on a number you enter.");
while(yesno.equalsIgnoreCase("Y"))
{
System.out.println("Please enter a number.");
number = keyboard.nextInt();
int row = 1;
int column = 1;
System.out.println(" |" + MAKETHISWORK + "\t"); //THIS IS WHERE I'M STUCK.
System.out.println("--------------------");
while(number>0)
{
row = 1;
while(row <= number)
{
System.out.print(row + "|");
column = 1;
while(column <= number)
{
System.out.print(row*column + "\t");
column ++;
} //END WHILE COLUMN <= NUMBER
System.out.println();
row ++;
} //END WHILE ROW <=NUMBER
System.out.println();
while(number>0)
{
number--;
}
} //END WHILE NUMBER >0
System.out.println("Would you like to enter another number? (Y/N) ");
yesno = keyboard.nextLine();
yesno = keyboard.nextLine();
} //END WHILE YESNO IS Y
while(yesno.equalsIgnoreCase("N"))
{
System.out.println("Thanks for participating!");
break;
}
}
}
