A Java collection of value pairs? (tuples?)

Question

I like how Java has a Map where you can define the types of each entry in the map, for example .

What I\'m looking for is a type

Answer 1

This is based on JavaHelp4u 's code.

Less verbose and shows how to do in one line and how to loop over things.

//======>  Imports
import java.util.AbstractMap.SimpleEntry;
import java.util.ArrayList;
import java.util.List;
import java.util.Map.Entry;

//======>  Single Entry
SimpleEntry myEntry = new SimpleEntry("ID", "Text");
System.out.println("key: " + myEntry.getKey() + "    value:" + myEntry.getValue());
System.out.println();

//======>  List of Entries
List> pairList = new ArrayList<>();

//-- Specify manually
Entry firstButton = new SimpleEntry("Red ", "Way out");
pairList.add(firstButton);

//-- one liner:
pairList.add(new SimpleEntry("Gray", "Alternate route"));  //Ananomous add.

//-- Iterate over Entry array:
for (Entry entr : pairList) {
    System.out.println("Button: " + entr.getKey() + "    Label: " + entr.getValue());
}
