Java lang.Integer.toBinaryString() 方法
java.lang.Integer.toBinaryString() 方法将整数参数表示为 2 进制数字的字符串形式。
示例
以下是 Java 中实现 toBinaryString() 方法的示例 -
import java.lang.*; public class IntegerDemo { public static void main(String[] args) { int i = 170; System.out.println("Number = " + i); /* returns the string representation of the unsigned integer value represented by the argument in binary (base 2) */ System.out.println("Binary is " + Integer.toBinaryString(i)); // returns the number of one-bits System.out.println("Num } }
输出
Number = 170 Binary is 10101010 Number of one bits = 4
让我们看另一个考虑负数的示例 -
示例
import java.lang.*; public class IntegerDemo { public static void main(String[] args) { int i = -35; System.out.println("Number = " + i); System.out.println("Binary is " + Integer.toBinaryString(i)); System.out.println("Number of one bits = " + Integer.bitCount(i)); } }
输出
Number = -35 Binary is 11111111111111111111111111011101 Number of one bits = 30
