Answer 2

There are several ways.Good things to use some collections classes from java.uitl package.
Following is the code to sort a string array which uses collections.

String[] strArray = new String[] {"z", "a", "C"};
Arrays.sort(strArray);
// [C, a, z]


// Case-insensitive sort
Arrays.sort(strArray, String.CASE_INSENSITIVE_ORDER);
// [a, C, z]

// Reverse-order sort
Arrays.sort(strArray, Collections.reverseOrder());
// [z, a, C]

// Case-insensitive reverse-order sort
Arrays.sort(strArray, String.CASE_INSENSITIVE_ORDER);
Collections.reverse(Arrays.asList(strArray));
// [z, C, a]


This works fine.

Answer 3

String array[] = { "May", "Lara", "Jason", "John", "Adam", "Angel"};

// Here we use a Linear Sort - the simplest sorting algorithm
int x;
String temp;
for(int i=0; i { x = i;
for(int j=i; j { if(array[j].compareTo( array[x] ) < 0)
{ x = j; }
}
temp = array[x];
array[x = array[i];
array[i] = temp;
}
