Converting back from toString to Object

Question

Is there any way to convert from toString back to the object in Java?

For example:

Map myMap = new HashMap

        

Answer 1

public class CustomMap<K, V> extends HashMap<K, V>{
    public String toString(){
        //logic for your custom toString() implementation.
    }
}

Have a class that extends HashMap and override the toString() method. Then you can do the following and achieve what you want to,

    CustomMap<String, String> myMap = new CustomMap<String, String>();
    myMap.put("value1", "test1");
    myMap.put("value2", "test2");
    String str = myMap.toString();
