java字节数组与数字数组互转

import java.nio.ByteBuffer;
import java.nio.FloatBuffer;



public class test {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub

        byte a[] ;
        byte k[]=new byte[2*4];
        float b[] = new float[2];
        float c[] = new float[2];
        for(int i=0;i<2;i++){
            b[i]=i+1010;
            
        }
        ByteBuffer bb = ByteBuffer.wrap(k);
        FloatBuffer fBuffer = bb.asFloatBuffer();
        fBuffer.put(b);
        
        FloatBuffer fb1 = bb.asFloatBuffer();
        fb1.get(c);    
        System.out.println("c1="+c[0]);
        System.out.println("c2="+c[1]);
