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...

可以看到,decode 方法首先对正负号和进制符号进行识别判断,最后将剩下的纯数值部分和得到的进制数值调用静态工厂方法 valueOf(string, int) 构造 Integer 对象。 4.4. valueOf 静态方法 Integer 类支持整型和字符串型参数的工厂方法,其中字符串型的工厂方法支持指定进制,并且会先使用 parseInt 方法解析出原始 int 数值...
In addition, this class provides several methods for converting an int to a String and a String to an int, as well as other constants and methods useful when dealing with an int. Implementation note: The implementations of the "bit twiddling" methods (such as highestOneBit and numberOfTraili...
