   @Terence: It does the same as the first: It creates an array of string array references, initialized to the values array1, array2, array3, array4 and array5 - each of which is in itself a string array reference. –

3. Removing an element from an Array (Java) - Stack Overflow

   stackoverflow.com/questions/642897

   To allocate a collection (creates a new array), then delete an element (which the collection will do using arraycopy) then call toArray on it (creates a SECOND new array) for every delete brings us to the point where it's not an optimizing issue, it's criminally bad programming.

4. Get only part of an Array in Java? - Stack Overflow

   stackoverflow.com/questions/11001720

   The length of an array in Java is immutable. So, you need to copy the desired part into a new array. Use copyOfRange method from java.util.Arrays class: int[] newArray = Arrays.copyOfRange(oldArray, startIndex, endIndex); startIndex is the initial index of the range to be copied, inclusive. endIndex is the final index of the range to be copied ...

5. How do I declare and initialize an array in Java? - Stack...

   stackoverflow.com/questions/1200621

   You can either use array declaration or array literal (but only when you declare and affect the variable right away, array literals cannot be used for re-assigning an array). For primitive types: int[] myIntArray = new int[3]; // each element of the array is initialised to 0 int[] myIntArray = {1, 2, 3}; int[] myIntArray = new int[]{1, 2, 3 ...

6. Finding the max/min value in an array of primitives using Java

   stackoverflow.com/questions/1484347

   Pass the array to a method that sorts it with Arrays.sort() so it only sorts the array the method is using then sets min to array[0] and max to array[array.length-1]. Share Improve this answer

8. How do you count the elements of an array in java

   stackoverflow.com/questions/4441099

   There's no distinction between that array and one which has explicitly been set with zero values. For example, these arrays are indistinguishable: int[] x = { 0, 0, 0 }; int[] y = new int[3]; Arrays in Java always have a fixed size - accessed via the length field. There's no concept of "the amount of the array currently in use".

9. How can I create a generic array in Java? - Stack Overflow

   stackoverflow.com/questions/529085

   import java.lang.reflect.Array; class Stack<T> { public Stack(Class<T> clazz, int capacity) { array = (T[])Array.newInstance(clazz, capacity); } private final T[] array; } As others have said generics are "erased" during compilation. So at runtime an instance of a generic doesn't know what its component type is.

10. What's the simplest way to print a Java array? - Stack Overflow

    stackoverflow.com/questions/409784

    Yes ! this is to be mention that converting an array to an object array OR to use the Object's array is costly and may slow the execution. it happens by the nature of java called autoboxing. So only for printing purpose, It should not be used. we can make a function which takes an array as parameter and prints the desired format as

11. Java, Shifting Elements in an Array - Stack Overflow

    stackoverflow.com/questions/7970857

    I have an array of objects in Java, and I am trying to pull one element to the top and shift the rest down by one. Assume I have an array of size 10, and I am trying to pull the fifth element. The fifth element goes into position 0 and all elements from 0 to 5 will be shifted down by one. This algorithm does not properly shift the elements:
