Question

Add code (see below for details) to the methods "set" and "get" in the following class, ArrayTen.java, so that these two methods catch the exception java.lang.ArrayIndexOutOfBoundsException if an illegal index is used, and in turn throw java.lang.IndexOutOfBoundsException instead.

Modify the "main" method to catch java.lang.IndexOutOfBoundsException and, when such an exception is caught, print the exception as well as the stack trace.

public class ArrayTen {

private String myData[] = new String[10];

public void set(int index, String value) {

myData[index] = value;

}

public String get(int index) {

return myData[index];

}

public static void main(String[] args) {

ArrayTen a = new ArrayTen();

a.set(10, "hello world");

System.out.println (a.get(10));

}

}

The expected output from your successful modification will be:

exception java.lang.IndexOutOfBoundsException

java.lang.IndexOutOfBoundsException

at ArrayTen.set(ArrayTen.java:10)

at ArrayTen.main(ArrayTen.java:25)

**Adding code means you are not allowed to modify or delete any of the existing code statements. You must add "try" and "catch" and any additional code needed to fulfill the requirements, without modifying the existing statements.

Please find your solution below and if doubt comment and do upvote.

public class ArrayTen {

private String myData[] = new String[10];

public void set(int index, String value) {
    try{
        myData[index] = value;
    }
    catch(Exception e){
        System.out.println(e);
        e.printStackTrace();
        
    }
}

public String get(int index) {
    String data="";
    try{
        data= myData[index];
    }
    catch(Exception e){
        System.out.println(e);
        e.printStackTrace();
        
    }
    return data;
}

public static void main(String[] args) {
    ArrayTen a = new ArrayTen();
    a.set(10, "hello world");
    System.out.println (a.get(10));
    
}

}
