Modify the code below to handle an array of strings and sort them A sample array: Jane Bob Susan Keith Edward Adam Your driver will need to display the unsorted and then the sorted array. Compile and test your code A sample run Sort2Driver Unsorted array: Jane Bob Susan Keith Edward Adam Sorted array: Adam Bob Edward Jane Keith Susan

Solution

In order to sort the string array, you can use a very simple method of Array class :

Arrays.sort(array);

Below is the code as per your requirement :

public class Sort
{
public static void sort(String[] list)
{
System.out.println(\"Unsorted array :\");
for(String s :list)
{
System.out.print(\" \"+s);
}
Arrays.sort(list);
System.out.println(\"\ Sorted array :\");
for(String s :list)
{
System.out.print(\" \"+s);
}
} // end sort method

} // end Sort class

public class SortDriver {
public static void main(String[] args)
{
String strArray={\"Jane\",\"Bob\",\"Susan\",\"Keith\",\"Edward\",\"Adam\"};
Sort.sort(strArray);
for(String s :strArray)
{
System.out.print(\" \"+s);
}
}//end main
}//end SortDriver
