The allocate() method of java.nio.IntBuffer Class is used to allocate a new int buffer next to the existing buffer. The new buffer’s position will be zero. Its limit will be its capacity. Its mark will be undefined. And each of its elements will be initialized to zero. It will have a backing array, and its array offset will be zero.
public static IntBuffer allocate(int capacity)
Parameter: This method takes the new buffer’s capacity, in int, as a parameter.
Return Value: This method returns the new int buffer.
Exception: This method throws the IllegalArgumentException if the capacity is a negative integer.
Below program illustrates the allocate() method:
IntBuffer: [11, 0, 19, 0, 0, 0, 0, 0, 0, 0]
Examples 2: To demonstrate IllegalArgumentException
Trying to allocate a Negative Integer Exception thrown: java.lang.IllegalArgumentException
