Java Integer compareUnsigned()用法及代码示例

java.lang包的Integer类的compareUnsigned()方法比较作为参数给出的两个整数值(x，y)，将这些值视为无符号，如果(x == y)，并且(x <y)，则返回零它返回小于零的值，如果(x> y)，则返回大于零的值。

用法:

public static int compareUnsigned(int x, int y)
参数：
x: the first int to compare
y: the second int to compare
返回：
This method returns the value zero if (x==y), 
if (x < y) then it returns a value less than zero 
and if (x > y) then it returns a value greater than zero,
treating the values(x, y) as unsigned.

例：展示java.lang.Integer.compareUnsigned()方法的用法。

// Java program to demonstrate working 
// of java.lang.Integer.compareUnsigned() method 
import java.lang.Integer; 
  
class Gfg { 
  
    // driver code 
    public static void main(String args[]) 
    { 
        int a = 100; 
        int b = 200; 
  
        // as 100 less than 200, Output will be a value less than zero 
        System.out.println(Integer.compareUnsigned(a, b)); 
  
        int x = 28; 
        int y = 28; 
  
        // as 28 equals 28, Output will be zero 
        System.out.println(Integer.compareUnsigned(x, y)); 
  
        int w = 15; 
        int z = 8; 
  
        // as 15 is greater than 8, Output will be a value greater than zero 
        System.out.println(Integer.compareUnsigned(w, z)); 
  
        int m = 15; 
        int n = -8; 
  
        // as 15 is greater than -8, 
        // but -8 will be treated as an unsigned number 
        // which will be greater than 15 
        // Output will be a value less than zero 
        System.out.println(Integer.compareUnsigned(m, n)); 
    } 
}

输出：

-1
0
1
-1
