How to transform List string to upper case in Java?
Let’s first create a List string:
List<String> list = Arrays.asList("David", "Tom", "Ken","Yuvraj", "Gayle");Now transform the above list to upper case:
list.stream().map(players -> players.toUpperCase())
To display, use forEach():
list.stream().map(players -> players.toUpperCase()) .forEach(players -> System.out.print(players + ""));
The following is an example to transform List string to upper case:
Example
import java.util.Arrays;
import java.util.List;
public class Demo {
public static void main(final String[] args) {
List<String> list = Arrays.asList("David", "Tom", "Ken","Yuvraj", "Gayle");
System.out.print("List = "+list);
System.out.print("
Uppercase strings = ");
list.stream().map(players -> players.toUpperCase()) .forEach(players -> System.out.print(players + ""));
}
}Output
List = [David, Tom, Ken, Yuvraj, Gayle] Uppercase strings = DAVID TOM KEN YUVRAJ GAYLE
