Thread: Hey Guys new to Java.. Got most of program done require a little assistance plz

hi there,The code will be showed below :

import java.util.*;
 
class Person{
 
private String Forename;
private String Surname;
private int Age;
private float Height;
private int personID;
Person(String Forename,String Surname,int Age,float Height,int personID){
 
this.Forename=Forename;
this.Surname=Surname;
this.Age=Age;
this.Height=Height;
this.personID=personID;
}
public void Display(){
System.out.println("person"+personID+"info:"+Forename+Surname+","+Age+","+Heigth+",");
}
}
public class PersonTest{
private static String Forename;
private static String Surname;
private static int Age;
private static int Height;
private static int personID;
public static void main(String args[]){
Person []persons=new Person[5];
for(int i=1;i<=5;i++){
Scanner scanner=new Scanner(System.in);
System.out.println("OutPut Forename:");
Forename=scanner.nextLine();
System.out.println("Output Surname:");
Surname=scanner.nextLine();
System.out.println("Output Age:");
Age=scanner.nextInt();
System.out.println("Output Height:");
Height=scanner.nextInt();
personID=i;
persons[i-1]=new Person(Forename,Surname,Age,Height,personID);
}
for(int i=0;i<5;i++){
persons[i].Display();
}
}
}

many thanks for your reply lewvan00. i see with your code that you kindly wrote to help me out, i dont see any access or mutator methods used. is there a way of accessing my person test by calling a persons age with getage? or someones details that way? i have ammended my program could you take a look to see if i can use the get methods please? much appreciated

import java.util.*;
public class Person
{
		private String Forename;
		private String Surname;
		private int Age;
		private int Height;
		private int personID;
 
	// Constructs a Person Test Class with the default value.
	Person(String Forename,String Surname,int Age,int Height,int personID)
	{
		this.Forename=Forename;
		this.Surname=Surname;
		this.Age=Age;
		this.Height=Height;
		this.personID=personID;
	}
 
		// Gets the First Name of the Person in the PersonTest
		public String getFName()
	{
		return Forename;
	}
 
			// Gets the Last Name of the Person in the PersonTest
		public String getLName()
	{
		return Surname;
	}
 
		// Gets the Height of the Person in the PersonTest
		public double getHeight()
	{
		return Height;
	}
 
		// Gets the Age of the Person in the PersonTest
		public int getAge ()
	{
		return Age;
	}
 
		public void Format()
	{
		System.out.println("person"+personID+"\tinfo:"+"\t" +Forename+ " \t"+Surname+"\t"+Age+"\t"+Height);
	}
 
 
}

import java.util.*;
public class PersonTest
{
 
	private static String Forename;
	private static String Surname;
	private static int Age;
	private static int Height;
	private static int personID;
 
	// Tests the methods of the Person File
	public static void main(String [] args)
	{
 
		//Creates an Array that counts the number of Persons in the Program
		Person [] persons = new Person [5];	
 
 
		for(int i=1;i<=5;i++)
		{
			Scanner scanner=new Scanner(System.in);
 
			System.out.println("Enter a Forename:");
			Forename=scanner.nextLine();
 
			System.out.println("Enter a Surname:");
			Surname=scanner.nextLine();
 
			System.out.println("Enter a Age:");
			Age=scanner.nextInt();
 
			System.out.println("Enter Height:");
			Height=scanner.nextInt();
 
			personID=i;
			persons[i-1]=new Person(Forename,Surname,Age,Height,personID);
		}
 
			for(int i=0;i<5;i++)
			{
				persons[i].Format();
			}	
 
 
 
	}
}

Actually,you can write a get and set method for each attribute of Person.
Like:

public String getForename()
{
return this.Forename;
}
public void setForename(String Forename){
this.Forename=Forename;
}

then,you can access or /and mutator whichever property of Person you want in the client code.

cheers dude i have ammeded my program with your guidence thank you.. i need to set a counter also so that the person test prints out the number of person entered onto the screen so something like. persons enter = 5

public class Person
{
		private String Forename;
		private String Surname;
		private int Age;
		private int Height;
		private int personID;
 
	// Constructs a Person Test Class with the default value.
	Person(String Forename,String Surname,int Age,int Height,int personID)
	{
		this.Forename=Forename;
		this.Surname=Surname;
		this.Age=Age;
		this.Height=Height;
		this.personID=personID;
	}
		// Gets the First Name of the Person in the PersonTest
		public String getForename()
	{
		return this.Forename;
	}
		public void setForename(String Forename)
	{
		this.Forename=Forename;
	}
 
			// Gets the Last Name of the Person in the PersonTest
		public String getSurname()
	{
		return this.Surname;
	}
		public void setSurname(String Surname)
	{
		this.Surname=Surname;
	}	
		// Gets the Height of the Person in the PersonTest
		public double getHeight()
	{
		return this.Height;
	}
		public void setHeight()
	{
		this.Height=Height;
	}	
		// Gets the Age of the Person in the PersonTest
		public int getAge ()
	{
		return this.Age;
	}
		public void setAge()
	{
		this.Age=Age;
	}	
		public void format()
	{
		System.out.println("person"+personID+"\tinfo:"+"\t" +Forename+ " \t"+Surname+"\t"+Age+"\t"+Height);
	}		
}
