This example initializes an array of bytes, reverses the array if the computer architecture is little-endian (that is, the least significant byte is stored first), and then calls the ToInt32(Byte[], Int32) method to convert four bytes in the array to an int.The second argument to ToInt32(Byte[], Int32) specifies the start index of the array of bytes. WebThis post will discuss how to convert the object array to an Integer array in Java. 1. Naive solution. A simple approach is to use a regular for-loop to iterate over the object array, and for every object, we cast it to Integer and assign it to the Integer array. 2. Using System.arraycopy () method.
