public static void main(String[] args) {
String s1 = “nag”;
String s2 = “nag”;
String s3 = s1;
String s4 = new String(“nag”);
String s5 = new String(“nag”);
System.out.println(s1 == s2);
System.out.println(s1 == s3);
System.out.println(s1.equals(s3));
System.out.println(s1 == s4);
System.out.println(s1.equals(s4));

how to sort hashmap in java

import java.util.HashMap;
import java.util.Map;
import java.util.TreeMap;

public class StringDemoExample {
public static void main(String[] args) {
Map<String, String> map = new HashMap<String, String>();
map.put(“9”, “EE”);
map.put(“8”, “DD”);
map.put(“7”, “CC”);
map.put(“6”, “BB”);
map.put(“5”, “AA”);
map.put(“4”, “bb”);
map.put(“3”, “dd”);
map.put(“2”, “aa”);
map.put(“1”, “cc”);
System.out.println(“Unsort HashMap values are …”);
printMap(map);
System.out.println(“Sorted HashMap…”);
Map<string, string=””> map1 = new TreeMap<string, string=””>(map);
printMap(map1);
}
private static void printMap(Map<string, string=””> map) {
for (Map.Entry entry : map.entrySet()) {
System.out.println(“Key : ” + entry.getKey() + ”   Value : “
+ entry.getValue());
}
}
}
OUTPUT:

Unsort HashMap values are …
Key : 3   Value :  dd
Key : 2   Value :  aa
Key : 1   Value :  cc
Key : 7   Value :  CC
Key : 6   Value :  BB
Key : 5   Value :  AA
Key : 4   Value :  bb
Key : 9   Value :  EE
Key : 8   Value :  DD
Sorted HashMap…
Key : 1   Value :  cc
Key : 2   Value :  aa
Key : 3   Value :  dd
Key : 4   Value :  bb
Key : 5   Value :  AA
Key : 6   Value :  BB
Key : 7   Value :  CC
Key : 8   Value :  DD
Key : 9   Value :  EE
