Source Link

Document

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

Usage

From source file:Main.java

public static void main(String[] args) {
    FloatBuffer floatBuffer = FloatBuffer.allocate(10);
    floatBuffer.put(1.23F);

    System.out.println(Arrays.toString(floatBuffer.array()));

}
