I want to store 4 arrays of int type. Now I don't know how to store them. The data in the array exceeds the range of byte. Please give me pointers.

Split an int into 4 bytes to store

Constructs a ByteArrayOutputStream
DataOutputStream
WriteInt () in turn
Convert ByteArrayOutputStream to byte [] and store it in rms

Corresponding read:
Read byte [], convert to ByteInputStream, convert to DataInputStream
ReadInt ()

Stored in String mode, for example, 3000 is stored as "3000", and it is also String after taking out, and then use Integer.parseInt ("3000"); becomes an integer.

Saving string is the most convenient.

Halo, the two upstairs, if you use string, the written code is not very troublesome?

Divide an int into 4 byte storage

  

This method is still very useful.


It is convenient to divide an int into >> operations and divide it into 4 bytes.

Convert format yourself
Or use stream

dataOutputStream.writeInt(int i);

dataInputStream.readInt();

Will it be troublesome to use String, don't you think?
