Write a Java application that asks a user to enter the data of a Person instance

Question

• Write a Java application that asks a user to enter the data of a Person instance: name and year_of_birth and then displays a message showing the age of the person. If the value of year_of_birth>2014 or year_of_birth<1900 prompt the user to reenter the value of year_of_birth and wait for the new value. Be sure your code compiles and runs as expected. Name your Java file Yournamehw2a.java.

• Write a Java interface named Searchable with two abstract methods: one named Way2Search that returns a String and another named MaxTime that returns an Integer. Be sure your code compiles and runs as expected. Name your Java file Searchable.java.

Explanation / Answer

Answer for 1 is:

class Yournamehw2a{

int Year;
String name;

Scanner sc=new Scanner();

System.out.println("Enter Name");
name=sc.readLine();
System.out.println("Enter Year");
age=sc.nextInt();

if(Year>2014||Year<1900){
System.out.println("Please re-enter your Date of Birth");
}

}

Answer for 2 is:

public interface Searchable {
        public String Way2Search();
        public Integer MaxTime();
}

class A implements Searchable {
    ...       
    public String way2Search() {
         //implement this method in one way here
    }
    public Integer maxTime() {
         //implement this method in one way here
    }
}

class B implements Searchable {
    ...   
    public String way2Search() {
         //implement this method in a different way here
    }
    public Integer maxTime() {
         //implement this method in a different way here
    }
}
