Java Program to check if any String in the list starts with a letter
First, create a List with String elements:
List<String> myList = new ArrayList<>();
myList.add("pqr");
myList.add("stu");
myList.add("vwx");
myList.add("yza");
myList.add("bcd");
myList.add("efg");
myList.add("vwxy");Use the startsWith() method to check if any of the above string in the myList begins with a specific letter:
myList.stream().anyMatch((a) -> a.startsWith("v"));TRUE is returned if any of the string begins with the specific letter, else FALSE.
The following is an example to check if any String in the list starts with a letter:
Example
import java.util.ArrayList;
import java.util.List;
public class Demo {
public static void main(final String[] args) {
List<String> myList = new ArrayList<>();
myList.add("pqr");
myList.add("stu");
myList.add("vwx");
myList.add("yza");
myList.add("bcd");
myList.add("efg");
myList.add("vwxy");
boolean res = myList.stream().anyMatch((a) -> a.startsWith("v"));
System.out.println("Do any string begins with letter v = "+res);
}
}Output
Do any string begins with letter v = true
