remove first character from list of string in java 8

To remove first character from list of string in java 8, we are using the Stream Api and subString() method.

• First, we take a Arraylist object with String type parameter.
• Now get the Stream data from List using list.stream() method.
• Inside map function, a.substring(1, a.length()) is called which return the string starting from the character at index 1 and ending index will be a.length().
• From collect() method, we collect all the list of string data.
• Print the list of string from second character.

import java.util.Arrays;
import java.util.List;
import java.util.stream.Collectors;

public class CharacterTest {
	public static void main(String[] args) {
		List<String> list = Arrays.asList("joe", "mary");
		
		List<String> names = list.stream().map(a -> a.substring(1, a.length())).collect(Collectors.toList());
		System.out.println("list of string are:- " + names);

	}
}

Output :-
list of string are:- [oe, ary]
