Hello I want to learn java.io ironically I could not find any tutorial cover most important classes of java.io in easy and simple way!!! sun's tutorial gives only one example about filestream? not good enough, thinking in java, to long example made me get lost? I am hoping to find a tutorial that give a good examples of how to use Reader Writer InpuStream OutputStream InputStreamReader OutputStreamWriter FileInputStream FileOutputStream FileReader FileWriter Is that too much to ask???
