Why different classes ? Re: Diff b/w DataOutputStream and PrintStream 14 Years Ago by daudiam Thanks. Does that mean that if we write the integer 2 using DataOutputStream, it'll write 0x0002, whereas if we use PrintStream, it'll convert it into the unicode code 0x32 and then use the UTF-8 or whatever is the default encoding of the platform to write that to the file ? Am i right ? Re: Diff b/w DataOutputStream and PrintStream 14 Years Ago by JamesCherrill Yes (except that ints in Java are 4 bytes, 0x00000002) Re: Diff b/w DataOutputStream and PrintStream 14 Years Ago by daudiam Thanks. Re: Diff b/w DataOutputStream and PrintStream 12 Years Ago by JamesCherrill Hello hajjanmu Welcome to Daniweb. I guess you did notice that this thread was marked "solved" 2 years ago? Re: Problem with writeInt 15 Years Ago by chaospie DataOutputStream will write the int as bytes to the file, that is why strange symbols are appearing.
