4,254 PointsAfter reformatting your code, I added comments for any issues I noticed.
public class Example {
public static void main(String[] args) {
System.out.println("we are making a new pen dispenser");
newPen dispenser = new newPen("yoda");
System.out.printf(" the dispenser is %s %n", dispenser.getCharacterName());
}
// these 2 lines should be within the main method body ^
String before = dispenser.swapHead(" Darth Vader");
System.out.printf( " it was %s but chris switched it to %s %n", before, dispenser.getCharacterName());
}
class newPen { // class names should start with a capital letter and be a noun (see #1)
private String characterName;
public newPen(String characterName) {
this.characterName = characterName;
}
public String getCharacterName() {
return characterName;
}
public String swapHead(String characterName) {
String originalCharacterName = this.characterName;
this.characterName = characterName;
retrun originalCharacterName; // misspelling on the word "return"
}
}
#1 Class Naming Conventions - When creating a new class, the name of the class should always start with a capital and be camelcase (see code conventions). Your class name looks to me like it should be a method name, as it's an action (create new pen). Instead, your class should be named "Pen," since you're creating a pen object. When renaming, make sure to change the name of your class file as well. (newPen.class
should be Pen.class
)
There may be more issues, but without seeing your stacktrace (or testing on my own), this is all I've noticed so far. Hope this helps get you started.
