java change array size code example

Example 1: java how to change the length of an array

The size of an array cannot be changed after instantiation
If you need to change the size, create a new array and copy the contents
or use an ArrayList which does require a set size

Example 2: resize array in java

int [] basedata = new int[10];

int [] original = basedata;
basedata = new int[12];

for(int i = 0; i < original.length; i++){
  basedata[i] = original[i];
}
