List – Integer Data Type
ListIntegerSorting.java
package com.narayanatutorial.primitive.sorting;
import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
public class ListIntegerSorting {
public static void main(String args[]) {
List<Integer> list = new ArrayList<Integer>();
list.add(123);
list.add(34);
list.add(567);
System.out.println("****Before Sorting****");
list.stream().forEach(name -> System.out.println(name));
Collections.sort(list);
System.out.println("****After Sorting****");
list.stream().forEach(name -> System.out.println(name));
list.clear();
list = new ArrayList<Integer>();
list.add(123);
list.add(34);
list.add(567);
//sorting using stream
System.out.println("**** Sorting using list stream ****");
list.stream().sorted().forEach(value->System.out.println(value));
}
}
Output
****Before Sorting**** 123 34 567 ****After Sorting**** 34 123 567 **** Sorting using list stream **** 34 123 567
List – String Data Type
ListStringSorting.java
package com.narayanatutorial.primitive.sorting;
import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
public class ListStringSorting {
public static void main(String args[]) {
List<String> list = new ArrayList<String>();
list.add("Tutorial");
list.add("Narayana");
list.add("Swamy");
System.out.println("****Before Sorting****");
list.stream().forEach(name -> System.out.println(name));
Collections.sort(list);
System.out.println("****After Sorting****");
list.stream().forEach(name -> System.out.println(name));
list.clear();
list = new ArrayList<String>();
list.add("Tutorial");
list.add("Narayana");
list.add("Swamy");
// sorting using stream
System.out.println("**** Sorting using list stream ****");
list.stream().sorted().forEach(value -> System.out.println(value));
}
}
Output
****Before Sorting**** Tutorial Narayana Swamy ****After Sorting**** Narayana Swamy Tutorial **** Sorting using list stream **** Narayana Swamy Tutorial
