How can i make this work

[Paul Dyer]

I have a java book which i am going through for a University course. Im in the 1st year so my programming is not brilliant. I have spent way to long on this question which is to design and build a program which will input the number of workers followed by their name, hours worked, hourly rate of pay, overtime rate of pay, status married or single for each. The main program must use seperate methods and appropriate parimeters. Ok so im stuck on the first part. I would like to put the number of workers in, then ask for the names of that number of workers. I know that i need to implement some sort of counter in there maybe using a for loop but it will not compile. I have only used a for loop with a number it will work towards and not a number to count off another input. I hope you get me and any help would be appreciated. Thanks. Here is my terrible work so far.

public static void main(String[]args)
	{
	
		Scanner input = new Scanner(System.in);
	
		int workers = 0;
		String name;

                System.out.print("Please input he number of workers ");
		workers = input.nextInt(); {

	
			for (workers = 1; <= count; worker++)
				System.out.print("Please input workers name ");
				name = input.next();
				workers++;
			}
	
	
	}
}

Hi Paul. Have you studied the Object Orientated Programming topic for Java yet? If not, you would need to start there.

For example:

public static void main(String[] args) { 

	Person p1 = new Person(26, "Ashley");
	Person p2 = new Person(120, "Madonna");

	// I want the age of Person 1 (p1)
	int age = p1.getAge();
	
	// Display this person's age
	System.out.print(age);
	// You can pass p1.getAge() directly to print if you wanted to, but to keep
	// it simple for now, do as above
	// System.out.print(p1.getAge());

} 

// Creating a new instance of Person would create a Person OBJECT
// You can create as many of these objects as you like and all
// will have unique instance variable values if implemented correctly
class Person {
	
	// private members of the Person Object
	// use private to ensure encapsulation and good OOP practice
	private int age;
	private String name;
	
	// When you create a new Person, you can pass parameters to the constructor
	Person(int age, String name) {
		
		// the use of 'this' tells the compiler than you are referring to the
		// private age member, not the age parameter, as they are named the same
		this.age = age;
		this.name = name;
	}

        // OR you can just have use a default constructor with no parameters (which is likely what you need)
        Person() { }
	
	// returns the age of this Person object
	int getAge() {
		return age;
	}

       // you can also set the age
       void setAge(int age) {
                this.age = age;
       }
}

NOTE: This is not directly what is asked of you in the assignment question, but this should help to get you started,

Hope it helps,
Ash

Hi, welcome to the Ranch!

One small admin matter: Please UseCodeTags to format your code nicely. It makes it much easier to read. I've gone in and done it for you this time :-)

You are right, you need a counter - and you need to keep that counter separate from the total number of workers the user just input!
What you've done in your code is overwritten the number of workers you just read in from the user with the number "1" to start looping.

Simplest fix: declare a new variable to keep track of which worker we are dealing with. If we are just going to use it within the loop, then lets declare it there.
The standard template for a for loop is:

for(int i=0; i<count; i++){
  
}

This declares a variable 'i', starts it at 0, and goes up to 'count' executing what is in the braces once for each value.
But what is count? It should be the number of times you want to loop, which in this case is the number you just input: workers.

for(int i=0; i<workers; i++){
  System.out.println("Please input name for worker#" + i) + ": ";
  
}

Next you will need a place to store ALL of the workers names.
The 'name' variable you have declared will store one of them.
To store multiple names, you will probably need an Array.

Thanks for the replies peeps i was not expecting a reply that quick. I am on a chapter in the book which is called sub programs, arrays are the next chapter and looking through this chapter there is nothing on oriented programming. I will try to implement the for loop the way Stefan has advised me. Here is the exact question.

Design, build and test a program to input the number of workers followed by their name, hours worked, hourly rate of pay, overtime rate of pay, status (married or single) for each. The main program must use separate methods and appropriate parameters. Suggested methods include:

calculate the gross pay (overtime rate is paid for any number of hours above 40)
calculate the amount of tax paid(25% if married and 30% if single)
display all the details as a payslip on the computer screen

HINT: You can pass String parameters too!

i have considered maybe i asked the first question wrong or i dont understand the question.

The chapters i studied before sub programs are getting started, The bricks and mortar of programming, beginning with design, selection, loops. When i have a problem i usually look back through my programs and they do normally answer that task, somehow. Sorry to go on and i do really appreciate the help. Ill jump on the for loop and try to get it to compile. Really appreciated. Thank you

Im not sure on how to use code tags but here it is and working i should be ok with the rest. Thanks again

import java.util.Scanner;
/**/
class MorePay
{

	public static void main(String[]args)
	{
		Scanner input = new Scanner(System.in);
	
		int workers, count, hWorked, hRate, oTime;
		String name, ms;
	
		System.out.print("Please input the number of workers ");
		workers = input.nextInt(); 
				
			for(int i=1; i<workers; i++){
				System.out.print("Please input name for worker " + i);
				name = input.next();
				
				System.out.print("Please input hours worked ");
				hWorked = input.nextInt();
				
				System.out.print("Please input your hourly rate ");
				hRate = input.nextInt();
				
				System.out.print("Please input overtime rate of pay ");
				oTime = input.nextInt();
				
				System.out.print("Are you married (M) OR Single (S) ");
				ms = input.next();
			}
	}
}

Welcome again

The code tags work like ↑ that. Well, you can read about them here and for advanced use here (scroll to the bottom). I deleted some excess blank lines which don't add to legibility.

Ty i will make sure i do this in the future. You peeps are really helpful

I will take more care in the future and apologize for using short hand words.
