Thread: method in class cannot be applied

Hi there, I am a total newbie. Learning java at uni. One of our questions on classes asks us to write some method statements. here is a snippet of the code:

PersonImproved agent1 = new PersonImproved("Natasha", 99);
  System.out.println(agent1);
  agent1.setName("Sophia");
  agent1.setAge(24);
  System.out.println(agent1);
 
  PersonImproved agent2 = new PersonImproved("Boris", 40);
  System.out.println(agent1.equals(agent2));
  System.out.println(agent1.isSameName(agent2));
  /*System.out.println(agent1.isSameAge(agent2));
   agent2.setName("Sophia");
   System.out.println(agent2.isSameName(agent1));
   agent2.setAge(21);
   System.out.println(agent2.isSameAge(agent1));
 
   System.out.println(agent1.isYoungerThan(agent2));
   agent1.setAge(42);
   agent2.setAge(42);
   System.out.println(agent1.isOlderThan(agent2));
   agent2.setAge(99);
   System.out.println(agent2.isOlderThan(agent1));
   System.out.println(agent1.isYoungerThan(agent2));*/
}}}
 
class PersonImproved
{private String name;
  private int age;
 
  public PersonImproved(String newName, int newAge)
  {name = newName;
    if (newAge >= 0)
      age = newAge;
    else
    {System.out.println("ERROR: Used a negative age.");
      System.exit(0);
    }
  }
 
  public String getName()
  {return name;
  }
 
  public void setName(String name)
  {
    this.name = name;
  }
 
  public int getAge()
  {return age;
  }
 
  public void setAge(int age)
  {
    this.age = age;
  }
 
 
 
  public boolean equals(String name, int age)
  {
    return (this.name == name && this.age == age);
  }
 
  public boolean isSameName(String name, int age)
  {
    return (this.name == name);
  }
 
  /*public boolean isSameAge(String name, int age)
   { 
   return (this.age == age);
   }
 
   public boolean isYoungerThan(String name, int age)
   {
   return (this.age < age);
   }
 
   public boolean isOlderThan(String name, int age)
   {
   return (this.age > age);
   }
 
   public String toString()
   {
   return name + " " + age;
   }*/
}

I am getting this error when compiling:

1 error found:
File: /Users/RichAnge/JPL/H274.java [line: 21]
Error: /Users/RichAnge/JPL/H274.java:21: isSameName(java.lang.String,int) in PersonImproved cannot be applied to (PersonImproved)

and I don't know what this means, can anyone inform me of what the error means so I can fix my code. thanks
(ps: i have some of the code commented out because I am working one line at a time, i hope that is not my problem lol).

It means the method isSameName requires a String and an int as parameters, but was given a PersonImproved object instead

...and welcome to the forum

thanks for your reply, it make a little bit of sense to me - I'm still learning :-)

You are welcome, good luck

all solved, thanks to you explaining that, i tried a couple of new things and I got a green pass! love seeing the green :-)
