Integer.numberOfLeadingZeros() Integer 方法: public static int numberOfLeadingZeros(int i) { // HD, Count leading 0's if (i <= 0) return i == 0 ? 32 : 0; int n = 31; if (i >= 1 << 16) { n -= 16; i >>>= 16; } if (i >= 1 << 8) { n -= 8; i >>>=...
Sometimes during dealing with legacy systems we need to pass numeric values in fixed length with leading zeros. Now in Java we just have an integer value. So how do we convert an integer in Java to a string value with fixed length of 9 with leading zeros. Here is a sample program that...
What you are doing requires a bitstring not an integer. If you really need to convert this bitstring to an integer then you need to do Integer.parseInt(string, 2) ; What you probably should do, if you really need to pass an integer, rather than the bitstring in string form is to ...
在下面的示例中,java.lang.Integer.numberOfLeadingZeros() 方法返回给定 int 值的二进制补码二进制表示中最左边一位之前的零位数。 import java.lang.*; public class MyClass { public static void main(String[] args) { //创建一个int值 int x = 75; //打印x的值,它的二进制 //表示和numberOfLeadin...
