Design and implement an application that reads a sequence of up to 25 pairs of names and postal (ZIP) codes for individuals. Store the data in an object designed to store a first name (string), last name (string), and postal code (integer). Assume each line of input will contain two strings followed by an integer value, each separated by a tab character. Then, after the input has been read in, print the list in an appropriate format to the screen.

String words[] = line.split("\t");

String fname = words[0];

String lname = words[1];

int numb = Integer.parseInt(words[2]);

al.add(p);

}

for(int i = 0; i < 25; i++) {

System.out.println("Person " + (i + 1) + ":");
