Prototype

public ByteBuffer put(ByteBuffer src)

Source Link

Document

Writes all the remaining bytes of the src byte buffer to this buffer's current position, and increases both buffers' position by the number of bytes copied.

Usage

From source file:Main.java

    Arrays.fill(paddings, padding);
    ByteBuffer buffer = ByteBuffer.allocate(len);

    buffer.put(tgt);
    buffer.put(paddings);

    return buffer.array();
