How do I loop through an enum in Java? [duplicate]

Question

Let's say I have an enum like so:

public enum Numbers {
    ONE("Uno "),
    TWO("Dos "),
    THREE("Tres ");
}

private final String spanishName;

Numbers(String spanishName) {
    this.spanishName = spanishName;
}

public String getSpanishName() {
    return spanishName;
}

Now I have a method that outputs a given variable.

public void output(String value) {
    printStream.print(value);
}

I want to use a for loop to output all the values in the enum. Something along the lines of this:

for(/*each element in the enum*/) {
    //output the corresponding spanish name
}

Ultimate I want the final output to be Uno Dos Tres. How can I do this using enums and a for loop?

Answer 1

for (Numbers n : Numbers.values()) {
   System.out.print(n.getSpanishName() + " ");
}

Answer 2

Use this:

for (Numbers d : Numbers .values()) {
     System.out.println(d);
 }

Answer 3

for (Numbers num : Numbers.values()) {
  // do what you want
}
