数组简单应用

public class test {
 private byte[] DealWithDate(byte[] data){
  byte [] DesData = new byte[1000];
  DesData[999] = 5;
  
  return DesData;
 }
 public static void main(String[] args) {
     byte [] data = new byte[100];
     test atest = new test();
     data = atest.DealWithDate(data);
    
     byte aVariable = data[999];
     System.out.print(aVariable);
 }
}
