      // This constructor has one parameter, name.
      System.out.println("Passed Name is :" + name );
   }

   public static void main(String []args) {
      // Following statement would create an object myPuppy
      Puppy myPuppy = new Puppy( "tommy" );
   }
}

Example 4: using class in java

public class HelloWorld {
  public static void main(String[] args) {
   
   
   class Number{
   
   	int number;
   
   	public boolean isPos(){
   		if(number > 0){
   			return true;
   		} else {
   			return false;
   		}
   		
   	}
   }
   
   Number myNumber = new Number();
   
   myNumber.number = 7;
   
   if(myNumber.isPos()){
   	System.out.println(myNumber.number + " is positive!!!");
   } else {
   	System.out.println(myNumber.number + " is not positive!!!");
   }
   
  }
}

Example 5: how to make a new class

#Use the class function and give the class a name
#next use the def __init__() to initilaize and give it some properties.
class Fruits():
  def __init__(self, name, colour, taste):
    self.name = name
    self.colour = colour
    self.taste = taste
#Now create an object by first calling the class
fruit1 = Fruits(apple, red, sweet)
print(fruit1.name)
#this will print the name which is apple
print(fruit1.colour)
#this will print the colour which is red
print(fruit1.taste)
#this will print the taste which is sweet

Example 6: create object and call method in java

MyClass **insert_name** = new MyClass();
        insert_name.**method_name**();
