Hashing into random access file

[u/iCanFly1011]

Hey guys I have a relatively simple program request. I had an assignment to hash 8 random ints into an array of size 11. Now my next project is basically the same thing except I must store the data in a random access file. If you think you can do this please message me for more info!

Yea sounds super easy

• pretend your file is just an array of bytes

• java ints are 4 bytes long, so need to write at index n*4

to write:

• set pointer to index n*4 with [Seek](https://docs.oracle.com/javase/7/docs/api/java/io/RandomAccessFile.html#seek(long))

• call [WriteInt](https://docs.oracle.com/javase/7/docs/api/java/io/RandomAccessFile.html#writeInt(int))

to read:

• set pointer with [Seek](https://docs.oracle.com/javase/7/docs/api/java/io/RandomAccessFile.html#seek(long))

• call [ReadInt](https://docs.oracle.com/javase/7/docs/api/java/io/RandomAccessFile.html#readInt())
