Below are the values contain in the HashMap
statusName {Active=33, Renewals Completed=3, Application=15}
Java code to getting the first Key (i.e Active)
Object myKey = statusName.keySet().toArray()[0];
How can we collect the first Key "Value" (i.e 33), I want to store both the "Key" and "Value" in separate variable.
Answer
You can try this:
Map<String,String> map = new HashMap<>();
Map.Entry<String,String> entry = map.entrySet().iterator().next();
String key = entry.getKey();
String value = entry.getValue();
Keep in mind, HashMap does not guarantee the insertion order. Use a LinkedHashMap to keep the order intact.
Eg:
Map<String,String> map = new LinkedHashMap<>();
map.put("Active","33");
map.put("Renewals Completed","3");
map.put("Application","15");
Map.Entry<String,String> entry = map.entrySet().iterator().next();
String key= entry.getKey();
String value=entry.getValue();
System.out.println(key);
System.out.println(value);
Output:
Active
33
