Java Integer compare()用法及代码示例

java.lang包的Integer类的compare()方法比较作为参数给出的两个整数值(x，y)，如果(x == y)则返回零，如果(x <y)则返回小于零，如果(x> y)，则返回大于零的值。

用法:

public static int compare(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.

例：展示java.lang.Integer.compare()方法的用法。

// Java program to demonstrate working 
// of java.lang.Integer.compare() method 
import java.lang.Integer; 
  
class Gfg { 
    // driver code 
    public static void main(String args[]) 
    { 
        int a = 10; 
        int b = 20; 
  
        // as 10 less than 20, Output will be a value less than zero 
        System.out.println(Integer.compare(a, b)); 
  
        int x = 30; 
        int y = 30; 
  
        // as 30 equals 30, Output will be zero 
        System.out.println(Integer.compare(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.compare(w, z)); 
    } 
}

输出：

-1
0
1
