Java String hashCode()用法及代碼示例

import java.io.*;
  
class GFG {
    public static void main(String[] args)
    {  
          // Creating the two String variable.
        String m = "A";
        String n="Aayush";
        
          // Returning the hash value of m variable
        System.out.println(m.hashCode());
         
          // Returning the hash value of n variable.
        System.out.println(n.hashCode());
    }
}

import java.io.*;
  
class GFG {
    public static void main(String[] args)
    {
        // Creating variable n of String type
        String n = "A";
  
        // Creating an object of String containing same
        // value;
        String m = new String("A");
  
        // Getting the hashvalue of object and the variable
        int hashValue_n = n.hashCode();
        int hashValue_m = m.hashCode();
  
        // Hash value is same whether is created from
        // variable or object.
        if (hashValue_n == hashValue_m) {
  
            // Printing the output when the output is same
            System.out.println("Values Same");
        }
        else {
            System.out.println("Not Same");
        }
    }
}
