Is there a Java equivalent of Python mapping?

Question

In Python, I use a dictionary display:

myAnonDict = {'foo': 23, 'bar': 'helloworld'}

Is there an equivalent in Java?

[edited "anonymous dictionary" to read "display dictionary"]

Answer 1

Map<String, String> myMap = new HashMap<String, String>();
myMap.put("foo", "23");
myMap.put("bar", "helloworld");

This is different from yours because you have heterogeneous data types, whereas my transactions are made only in Lines. You may actually have mixed collections in Java, but I hate doing it. The type of lesion is the goal of strong typing.

Answer 2

Apache commons lang will allow you to do something similar (string based example, configurable)

Here is the code:

import java.util.Map;
import org.apache.commons.lang.ArrayUtils;

public class ArrayToMapExample {

    public static void main(String[] args) {
        Map dict = ArrayUtils.toMap(new String[][]{{"United States", "New York"},
                            {"United Kingdom", "London"},
                              {"Netherland", "Amsterdam"},
                              {"Japan", "Tokyo"},
                              {"France", "Paris"}});


        System.out.println("Capital of France is " + dict.get("France"));
    }
}

AbacusUtil , a generic Java programming library that provides many of the most commonly used methods to make Java programming more fun and more productive:

    Map<String, Integer> map = asMap("abc", 23, "bar", 7);
