Regular Expression "$" (dollar) Metacharacter in Java
The subexpression/metacharacter “$” matches the end of a line.
Example 1
import java.util.regex.Matcher; import java.util.regex.Pattern; public class EndWith { public static void main( String args[] ) { String regex = "Tutorialspoint$"; String input = "Hi how are you welcome to Tutorialspoint"; Pattern p = Pattern.compile(regex); Matcher m = p.matcher(input); int count = 0; while(m.find()) { count++; System.out.println("Number of matches: "+count); } } }
Output
Number of matches: 1
Example 2
The following Java program accepts 5 strings from the user and prints the strings ending with a digit.
import java.util.Scanner; import java.util.regex.Matcher; import java.util.regex.Pattern; public class EndingwithDigit { public static void main( String args[] ) { String regex = "^.*[0-9]$"; Scanner sc = new Scanner(System.in); System.out.println("Enter 5 input strings: "); String input[] = new String[5]; for (int i=0; i<5; i++) { input[i] = sc.nextLine(); } //Creating a Pattern object Pattern p = Pattern.compile(regex); System.out.println("Strings ending with digits: "); for(int i=0; i<5;i++) { //Creating a Matcher object Matcher m = p.matcher(input[i]); if(m.matches()) { System.out.println(m.group()); } } } }
Output
Enter 5 input strings: sample string 1 sample string 2 test data hello 3264533 3546373 7653 Strings ending with digits: sample string 1 sample string 2 3264533 3546373 7653
