Map comparison
In this chapter you will learn:
Map equals
equals() methods tells us if two maps are equal. In order to be equal they must have the same key-value pairs.
import java.util.HashMap;
import java.util.Map;
/*from j a va2 s . c o m*/
public class Main {
public static void main(String[] a) {
Map<String,String> map = new HashMap<String,String>();
map.put("key1", "value1");
map.put("key2", "value2");
map.put("key3", "value3");
Map<String,String> map2 = new HashMap<String,String>();
map2.put("key2", "value2");
map2.put("key1", "value1");
map2.put("key3", "value3");
System.out.println(map1.equals(map2));
}
}
The code above generates the following result.
