Get and Set float type data in a ByteBuffer

import java.nio.ByteBuffer; publicclass Main { publicstaticvoid main(String[] argv) throws Exception { ByteBuffer buf = ByteBuffer.allocate(100); // Put values of different types  buf.putFloat(12.3F); // Reset position for reading  buf.flip(); // Retrieve the values float f = buf.getFloat(); } }
