By: Grant Braught in Java Tutorials on 2011年01月27日 [フレーム]

This sample Java program demonstrates the use of Array. In this case an int Array to be able to insert or delete an element at a specific index. To be able to search or print the array.

public class IntArrayOperations {
 public static int arrayMaximum(int[] a) {
	// maxIndex is the index of the largest
	// value seen so far. Thus, a[maxIndex] is
	// the largest value seen so far.
	int maxIndex = 0;
	// Check every value, always keeping track of
	// the index of the largest value seen so far.
	for (int i=1; i a[maxIndex]) {
		maxIndex = i;
	 }
	}
	return maxIndex;
 }
 public static int arrayMinimum(int[] a) {
	int minIndex = 0;
	for (int i=1; iindex; i--) {
	 a[i] = a[i-1];
	}
	// Put the value in its spot.
	a[index] = value;
 }
 public static void arrayDelete(int[] a, int index) {
	// Move all values that appear at an index i that
	// is greater then index down by one index. This
	// will overwrite the element at index and leave 
	// the last element empty.
	for (int i=index+1; i
