Java8_forEachExample
This example forEach() easily traverse the collection . You can compare this
example using java 7 .
package Java8;
import java.util.List;
import java.util.ArrayList;
import java.util.HashMap ;
import java.util.Map;
public class HelloJava8 {
public static void getDataList() {
List
items.add("A");
items.add("B");
items.add("C");
items.add("D");
items.add("E");
items.add("M");
items.add("N");
items.add("Z");
items.forEach((i)->System.out.println("List::"+i ));
}
public static void getDataHashMap (){
Map < String , Integer > ma= new HashMap<>() ;
ma.put("A", 9);
ma.put("B", 7);
ma.put("C", 11);
ma.put("G", 5);
ma.forEach((k , v)->System.out.println("Key::"+k +"--" + "Value::" +v ));
}
public static void main(String[] args) {
// TODO Auto-generated method stub
getDataList();
getDataHashMap();
}
}
When you run this code this will be the out put.
List::A
List::B
List::C
List::D
List::E
Key::A--Value::9
Key::B--Value::7
Key::C--Value::11
Key::G--Value::5
