Using generic methods to print array of different types
<![CDATA[
public class MainClass {
// generic method printArray
public static <E> void printArray(E[] inputArray) {
// display array elements
for (E element : inputArray)
System.out.printf("%s ", element);

Double[] doubleArray = { 1.1, 2.2, 3.3, 4.4, 5.5, 6.6, 7.7 };

System.out.println("Array integerArray contains:");
printArray(integerArray); // pass an Integer array
System.out.println("\nArray doubleArray contains:");
printArray(doubleArray); // pass a Double array
System.out.println("\nArray characterArray contains:");
printArray(characterArray); // pass a Character array
} // end main
}
Array integerArray contains:
1 2 3 4 5 6
Array doubleArray contains:
1.1 2.2 3.3 4.4 5.5 6.6 7.7
Array characterArray contains:
H E L L O
