Question

For this question, consider names of cities that are made from any number of words where the first letter is always in uppercase and the words are separated by a space Implement a regular expression as a Java String p like so String p " such that is a regular expression pattern that will match any String that contains the name of a city and only such strings. Your answer must include the whole line of code above, meaning that themust be properly backslash-escaped both in terms of backslash escapes required for regular expressions and any backslash escapes required to put the expression inside the quotes above. Your answer will be inserted automatically into a test method match) like so public void match(String s) String p = System.out.printin(s.matches(p)? "match" S: "does not match" + S); the test cases will invoke this method. Example The following are valid city names . Ho Chi Minh City Palmerston North . Auckland The following are invalid city names: sydney . New york For example: . san Francisco Test Result match("Auckland")match Auckland match("sydney"); does not match sydney Answer (penalty regime: 0 %) 1 public void match(String s) string p - “ 4 System.out.println(s.matches (p)? "match "S: "does not match"s);

Answer 1

Below is the complete code of java along with attached output shot.

// Test.java
import java.util.Scanner;

public class Test {

public static void main(String[] args) {
Test t = new Test();
System.out.println("Enter the city name.");
Scanner sc = new Scanner(System.in);
String str = sc.nextLine();
// trim function to remove extra spaces from end or begning of string
System.out.println(t.match(str.trim()) ? "match " + str : "does not match " + str);
}

boolean match(String str) {
boolean result = false;
String temp[] = str.split(" ");
for (String ss : temp) {
if (Character.isUpperCase(ss.charAt(0))) {
result = true;
} else {
result = false;
break;
}
}
return result;
}
}

// Output :

Output Test (run) Enter the city name sydney does not match sydney BUILD SUCCESSFUL (total time 9 seconds)

Output Test (run) Enter the city name Ho Chi Minh City match Ho Chi Minh City BUILD SUCCESSFUL (total time 12 seconds)
