Source Link

Document

Writes floats from the given float array, starting from the specified offset, to the current position and increases the position by the number of floats written.

Usage

From source file:Main.java

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

    floatBuffer.put(new float[] { 1.23F, 2.13F, 3.13F, 2.13F, }, 0, 2);

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

}
