Little help please

Code :

---

import java.util.Scanner;
 
public class Donations
{
   public static void main(String[] args)
   {
      Scanner keyboard= new Scanner (System.in);
      String donorName;
      int donationAmount, donationQuantity=0, maxDonation=0;
 
      do
      {
 
         System.out.println("Please enter your name");
         donorName=keyboard.nextLine();
 
         System.out.println("Please enter donation amount");
         donationAmount=keyboard.nextInt();
 
         donationQuantity=donationQuantity+1;
 
         maxDonation +=donationAmount;
 
 
      }
      while (maxDonation<500);
 
      System.out.println("It took " + donationQuantity + " donations to reach the £500");
 
 
   }//main
}//class

For some reason when the program loops the second time for a new customer to enter the name, the amount prompt appears directly below it, therefore not being able to enter the 2nd name. Any ideas guys?

The Scanner class's nextInt() method leaves the lineend character in its buffer. The next call to the nextLine() method reads and returns that lineend character as an empty line.
Add a call to the nextLine() method after calling the nextInt() method to read the lineend character.

I changed them about, now this is my output:

Please enter donation amount
65

Please enter your name
Please enter donation amount


Therefore wont let me enter my name, sorry I am a beginner.

Please post the current version of the code.

The order of the calls won't change what the nextInt() method does. It still leaves the lineend character in its buffer.
To see that nextLine() reads an empty line, add a println() statement to print out its value after it is read.

Code :

---

import java.util.Scanner;
 
public class Donations
{
   public static void main(String[] args)
   {
      Scanner keyboard= new Scanner (System.in);
      String donorName;
      int donationAmount, donationQuantity=0, maxDonation=0;
 
      do
      {
 
         System.out.println("Please enter donation amount");
         donationAmount=keyboard.nextInt();
 
         System.out.println("\nPlease enter your name");
         donorName=keyboard.nextLine();
 
 
         donationQuantity=donationQuantity+1;
 
         maxDonation +=donationAmount;
 
 
      }
      while (maxDonation<500);
 
      System.out.println("It took " + donationQuantity + " donations to reach the £500");
 
 
   }//main
}//class

So, why is it reading an empty line tho, why won't it wait for the user input?

Create two scanner objects, one for integers and one for strings. Then you can avoid the whole issue. Scanner has issues when one object is used for both nextLine() and nextInt().

donorName=keyboard.next(); fixed the issue instead of donorName=keyboard.nextLine();

That would work as long as the name doesn't have any spaces in it.
