java.lang.Class类的hashCode()方法用于获取此实体的hashCode表示形式。此方法返回一个整数值，即hashCode。
用法:
public int hashCode()
参数：此方法不接受任何参数。
返回值：此方法返回一个整数值，即hashCode。
下面的程序演示了hashCode()方法。
范例1：
// Java program to demonstrate hashCode() method
public class Test {
public static void main(String[] args)
throws ClassNotFoundException
{
// returns the Class object for the class
// with the specified name
Class c1 = Class.forName("java.lang.String");
System.out.println("Class represented by c1:"
+ c1);
// hashCode method on c1
System.out.println("HashCode value:"
+ c1.hashCode());
}
}
输出：
Class represented by c1:class java.lang.String
HashCode value:589431969
范例2：
// Java program to demonstrate hashCode() method
public class Test {
public static void main(String[] args)
throws ClassNotFoundException
{
// returns the Class object for the class
// with the specified name
Class c1 = int.class;
System.out.println("Class represented by c1:"
+ c1);
// hashCode method on c1
System.out.println("HashCode value:"
+ c1.hashCode());
}
}
输出：
Class represented by c1:int
HashCode value:589431969
