Java Integer compareTo()方法
原文:https://www . geesforgeks . org/Java-integer-compare to-method/
java.lang 包的 Integer 类的 compareTo() 方法对两个 Integer 对象进行数值比较，如果这个 Integer 等于参数 Integer，则返回值 0；如果该整数在数值上小于参数整数，则该值小于 0；如果此整数在数字上大于参数整数(有符号比较)，则为大于 0 的值。
语法:
public int compareTo(Integer anotherInt)
Parameter :
anotherInt- : the Integer to be compared.
Return :
- This method returns the value 0 if this Integer is
equal to the argument Integer;
- a value less than 0 if this Integer is
numerically less than the argument Integer;
- and a value greater than 0 if this Integer is
numerically greater than the argument Integer
(signed comparison).
示例:展示Java . lang . integer . compare To()方法的工作。
// Java program to demonstrate working
// of java.lang.Integer.compareTo() method
import java.lang.Integer;
class Gfg {
// driver code
public static void main(String args[])
{
Integer a = new Integer(10);
Integer b = new Integer(20);
// as 10 less than 20, Output will be a value less than zero
System.out.println(a.compareTo(b));
Integer x = new Integer(30);
Integer y = new Integer(30);
// as 30 equals 30, Output will be zero
System.out.println(x.compareTo(y));
Integer w = new Integer(15);
Integer z = new Integer(8);
// as 15 is greater than 8, Output will be a value greater than zero
System.out.println(w.compareTo(z));
}
}
输出:
-1
0
1
