Common Array Algorithms
2. Counting Loops and Arrays
Answer:
This sounds like a good place for a counting loop.
Counting Loops and Arrays
public class CountArray { public static void main ( String[] args ) { int[] egArray = { 2, 4, 6, 8, 10, 1, 3, 5, 7, 9 }; for ( int index = ; ; ) { System.out.println( ); } } } |
In Java, the index of an array starts at 0 and counts up to one less than the number of elements in the array. Counting loops can easily do that. The example program (above) does that, except for a blank or two.
The variable egArray
refers to an array object that has been constructed using an initializer list.
Question 2:
Fill in the blanks so that the program prints out every element, in order. You may wish to copy and paste from the following:
0
index++
egArray[index]
index < 10
(Highlight a string and then use use "copy" and "paste" commands from the "edit" menu of your browser to paste the string into a blank. Or use control-c and control-v as shortcuts for copy and paste.)
