insert an element in an array in java code example
Example 1: java insert array
int arr[] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };
int newarr[] = new int[maxSize];
newarr[pos] = n;
for (i = 0; i < maxSize; i++) { newarr[i] = arr[i]; }
Example 2: java add element to existing array
String[] rgb = new String[] {"red", "green"};
String[] rgb2 = new String[rgb.length + 1];
System.arraycopy(rgb, 0, rgb2, 0, rgb.length);
rgb2[rgb.length] = "blue";
rgb = rgb2;
Example 3: how to insert a 0 in an array java
public static int[] addPos(int[] a, int pos, int num) {
int[] result = new int[a.length];
for(int i = 0; i < pos; i++)
result[i] = a[i];
result[pos] = num;
for(int i = pos + 1; i < a.length; i++)
result[i] = a[i - 1];
return result;
}
