如何将我的绝对数字转换为ascii数字（最好没有循环）？

Question

我只想让程序得到它的绝对值，并在ASCII表中打印它对应的字符。绝对值的原因是负数输入。

    Scanner scan = new Scanner(System.in);
    
    int num1, num2;

    System.out.println("Enter first number:");
    num1 = scan.nextInt();

    System.out.println("Enter second number:");
    num2 = scan.nextInt();
    
    int largestNum = Math.max(num1, num2); //scan who big num
    
    int absNum = Math.abs(largestNum);

    char ch = (char) absNum;
    int castAscii = (int) ch;

    System.out.println("Largest Number: " + absNum);
    System.out.println("The absolute Number is " + absNum);// display large num
    System.out.println("The ASCII value of "+ castAscii + "is: " + castAscii);
    
    
    
    
    
scan.close();
    
    
}

Answer 1

由于数字在ascii表中是有序出现的，所以只需这样做就可以获得数字的char值：

int absNum = Math.abs(largestNum);

char ch = absNum+'0';
int castAscii = (int) ch;

假设absnum是一个数字，否则不能用char表示。
