What Causes "'Void' Type Not Allowed Here" Error

What causes 'void' type not allowed here error

If a method returns void then there is nothing to print, hence this error message. Since printPoint already prints data to the console, you should just call it directly:

printPoint (blank); 

Why am I getting 'void' type not allowed here?

void on a method means no return value.

System.out.println is void and does therefore not return a value.

Therefore the + does not have anything to add, and the compiler complains.

Getting Error void type not allowed here

static void SortArray(int[] a ,int size)

1. instead of void , use int[]
   
   static int[] SortArray(int[] a ,int size)

---

 case 2:{....
                }
            }
        }
        return a;
    }

then add return a; in your method as shown above

This will solve void type is not allow here

• using void in a method mean you wont return anything from that
  method.
• after adding int[] static int[] SortArray(int[] a ,int size) in your method ,your are telling compiler that after sorting your array , u will return array.

I'm Getting The Error: 'void' type not allowed here

My original answer was indeed wrong. If you need to return void, instead of printing it, replace in the array (or create a new array with capitalized Strings):

public void capitalize(String[] name) {
  String s = "";
  for (int i = 0; i < name.length; i++) {
     s = name[i];
     s = s.substring(0,1).toUpperCase() + s.substring(1).toLowerCase();
     name[i] = s;
  }                    
}

Then, in your print statement, print out name[j] (or whatever you called the new array, if you want to preserve original).

Error: 'void' type not allowed here

The error message is telling you exactly what is wrong -- you're trying to extract a result from a method that does not return a result.

Instead, have the mileage() method return a String, not print out a String.

public String mileage() {
    return String.valueOf(miles);
}

Myself, I'd make this a getter method, and instead would do:

public int getMiles() {
    return miles;
}

What causes error 'void' type not allowed here and how do I fix it?

LN.Totalbayar= Integer.parseInt(txtTotalBayar.setText(sum+""));

The return type of setText is void. Integer.parseInt expects a String. Setters don't usually return anything. Their purpose is to change a value, not retrieve it.

I'm not sure why you are trying to change txtTotalBayar while also parsing its value, so it is hard for me to say what the right thing to do is, but perhaps you want something like:

txtTotalBayar.setText(sum+"");
LN.Totalbayar= Integer.parseInt(txtTotalBayar.getText());
