Example 1

//import statement
import java.lang.reflect.Method;
public class ReflectMethodhashCodeExample1 {
   public static void main(String[] args) {
      Method[] mthd = DemoX11.class.getMethods();  //gets the methods
      System.out.println(mthd[1].hashCode());
   }
}

class DemoX11 {
   private String Field;

   public String getSampleField() {
      return Field;
   }

   public void setSampleField(String Field) {
      this.Field = Field;
   } 
}

Example 2

//import statements  
import java.lang.reflect.Constructor;
import java.lang.reflect.Method;  //import Method class of reflect
import java.lang.reflect.Modifier;

public class ReflectMethodhashCodeExample2   {

   public static void main(String[] args) {

      Method[] mthd = DemoXY1.class.getMethods();
      for (Method mthd1 : mthd) {
        
          System.out.println("Hash code : " +mthd1.hashCode());
      }
   }
}

class  DemoXY1 {
   private String Field;

   public DemoXY1() throws ArrayIndexOutOfBoundsException {
   }

   private DemoXY1(String Field){
      this.Field = Field;
   }

   public String getSampleField() {
      return Field;
   }
