java中两个byte数组实现合并的示例

/** 
 * 
 * @param data1 
 * @param data2 
 * @return data1 与 data2拼接的结果 
 */ 
public static byte[] addBytes(byte[] data1, byte[] data2) { 
 byte[] data3 = new byte[data1.length + data2.length]; 
 System.arraycopy(data1, 0, data3, 0, data1.length); 
 System.arraycopy(data2, 0, data3, data1.length, data2.length); 
 return data3; 
 
}
