Java整数比较（）方法

Java.lang包的Integer类的compare()方法比较给定的两个整数值(x, y)
作为参数，如果 (x==y) 则返回零值，如果 (x < y) 则返回小于零的值并且
if (x > y) 则返回一个大于零的值。

句法 ：

public static int compare(int x, int y)
Parameter :
x : the first int to compare
y : the second int to compare
Return :
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.

示例：显示Java.lang.Integer.compare()方法的工作。

// 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
