Need help with creating array of type object

[riz618]

Hi All,

I dont very well understand how exactly do i create a array of type object. Below i will paste what i am trying to do, so that you have a good idea of what i am talking about.

Thanks

Code:

package Person;

public class PersonTest 
{
	static Person[] p;
	
	public PersonTest()
	{
		p=new Person[3];
	}
	
	public void insert()
	{
		for(int i=0;i<(p.length-1);i++)
		{
			p[i].name="i";
			p[i].ID=i;
			
		}
	}
	public void display()
	{for(int i=0;i<(p.length-1);i++)
	{
		System.out.println(p[i].name);
		System.out.println(p[i].ID);
		
	}
		
	}


	public static void main(String[] args)
	{
		PersonTest t = new PersonTest();
		t.insert();
		t.display();

	}

}

Code:

package Person;

public class Person
{
	String name;
	int ID;
	public Person()
	{
		
	}

}

Code:

// Each element in this array is null:
p=new Person[3];
...
// Instantiate array element "i":
p[i] = new Person();
p[i].name="i";
p[i].ID=i;

Based on what you said i have done it and my new code is as under, still it says method Insert not defined for class PersonTest

package Person;

public class PersonTest
{
static Person[] p;

public PersonTest()
{
p=new Person[3];


public void insert()
{
for(int i=0;i<p.length-1;i++)
{
p[i]=new Person();
}
}
for(int i=0;i<(p.length-1);i++)
{
p[i].name="i";
p[i].ID=i;

}
}
public void display()
{for(int i=0;i<(p.length-1);i++)
{
System.out.println(p[i].name);
System.out.println(p[i].ID);

}

}


public static void main(String[] args)
{
PersonTest t = new PersonTest();
t.insert();
t.display();

}

}

You put the insert method inside the constructor. This is not allowed.
So change this:

Code:

public PersonTest()
{
    p=new Person[3];

    public void insert()
    {
        for(int i=0;i<p.length-1;i++)
        {
            p[i]=new Person();
        }
    }

    for(int i=0;i<(p.length-1);i++)
    {
        p[i].name="i";
        p[i].ID=i;
    }
}

to this:

Code:

public PersonTest()
{
    p=new Person[3];
}

public void insert()
{
    for(int i=0;i<p.length-1;i++)
    {
        p[i]=new Person();
    }

    for(int i=0;i<(p.length-1);i++)
    {
        p[i].name="i";
        p[i].ID=i;
    }
}
