How to right-align output numbers in java

The method to right-align output numbers in Java is to use printf(). The specific steps are as follows: use the d format specifier to specify the width of the output field as 10, and use the integer d format specifier to format the number. The specified width of 10 ensures that the numbers are right-justified in the field. If the number has fewer digits than the field width, it will be padded with spaces to reach the specified width. If the number has more digits than the field width, the field will automatically expand to accommodate the number.

How to right-align output numbers in Java

In Java, you can use printf() Method right aligns numeric output.

The following example demonstrates how to use printf() to right-align output numbers:

public class RightAlignNumbers {

    public static void main(String[] args) {
        // 要右对齐的数字
        int number = 12345;

        // 使用 printf() 方法右对齐输出数字
        // %10d 指定了输出字段的宽度为 10，并将数字右对齐
        System.out.printf("%10d", number);
    }
}

Output results:

<code>    12345</code>

Explanation:

• The d format specifier specifies the width of the output field to be 10 characters and uses the integer d format specifier format digitization.
• 10 The specified width ensures that the numbers are right-justified in the field.
• If the number has less digits than the field width, it will be padded with spaces to reach the specified width.
• If the number of digits is greater than the field width, the field will automatically expand to accommodate the number.
