Java Vector类的
hashCode()方法用于获取位于以下位置的向量的哈希码值
语法:
以下是
hashCode()方法的声明:
参数:
此方法不接受任何参数。
返回:
hashCode()方法返回此向量的哈希码值。
例外:
NA
兼容版本:
Java 1.2及更高版本
示例1:
import java.util.*;
public class VectorHashCodeExample1 {
public static void main(String arg[]) {
//Create an empty vector
Vector<Integer> vec = new Vector<>();
//Add element in the vector
vec.add(1);
vec.add(-2);
vec.add(3);
vec.add(-4);
vec.add(5);
//Printing the element
System.out.println("Element in vector = "+vec);
//Get the hashcode for this vector
System.out.println("HashCode vector = "+vec.hashCode());
}
}
输出:
Element in vector = [1, -2, 3, -4, 5]
HashCode vector = 29495854
示例2:
import java.util.*;
public class VectorHashCodeExample2 {
public static void main(String arg[]) {
//Create an empty vector
Vector < String > colors = new Vector < String > ();
//Add elements in the vector
colors.add("White");
colors.add("Green");
colors.add("Black");
colors.add("Pink");
//Print the elements of this vector
System.out.println("Color elements in vector: " +colors);
//Get the hash code value for this vector
System.out.println("HashCode: " +colors.hashCode());
}
}
输出:
Color elements in vector: [White, Green, Black, Pink]
HashCode: 1877005970
示例3:
import java.util.*;
public class VectorHashCodeExample3 {
public static void main(String arg[]) {
//Create an empty vector
Vector<String> vec = new Vector<>();
//Add element in the vector
vec.add("@");
System.out.println(vec.hashCode());
vec.add("%");
System.out.println(vec.hashCode());
vec.add("=");
System.out.println(vec.hashCode());
}
}
输出:
