StringformattedNumberWithLeadingZeros=String.format("%02d",number); 1. 步骤4:打印格式化后的结果 最后,我们可以通过打印格式化后的结果来查看自动补零的效果。 AI检测代码解析 System.out.println(formattedNumberWithLeadingZeros); 1. 状态图 下面是一个状态图,展示了整个自动补零的过程: 定义一个数值变量使用St...
We can also specify the total number of characters in the formatted text using the format%X.YE, whereXis the minimum number of characters andYis the number of decimal points in the formatted string. If the formatted number has fewer characters thanX, it pads the result with spaces: publicsta...
NumberOfLeadingZeros(Int32) Returns the number of zero bits preceding the highest-order ("leftmost") one-bit in the two's complement binary representation of the specified int value. NumberOfTrailingZeros(Int32) Returns the number of zero bits following the lowest-order ("rightmost") one-...
System.out.format("%d%n", -553); System.out.format("%(d%n", -553); } The example presents a few flags of the string format specifier. System.out.format("%010d%n", 553); The0flag will cause the output to be padded with leading zeros to the minimum field width. Our number has...

If the '0' flag is given then the output will be padded with leading zeros to the field width following any indication of sign. If '(', '+', ' ', or ',' flags are given then a FormatFlagsConversionMismatchException will be thrown. 'x' '\u0078' Formats the argument as an ...
The following program shows some of the formatting that you can do with format. The output is shown within double quotes in the embedded comment: import java.util.Calendar; import java.util.Locale; public class TestFormat { public static void main(String[] args) { long n = 461012; System...
