using java File Details – Build a class called FileDetails.java. When you instantiate this class and give it a filename, it will report back the size of the file, whether the file is Readable and whether the file is Writeable; plus any other file information that you might deem important. This cd goes in main FileDetails fd=newFileDetails(“anyfile.doc”); All other code goes in the constructor. Write a String to a File using PrintStream – This time build a class WriteString. This...

Using Java 1.) Write Integers to a File – This time build a class WriteInts. This class, when instantiated, will create a new file and write an array of integers to this new file. All the code to write the data to the file goes in the Constructor. [i.e. // This code goes in main() int myArr[] = {16, 31, 90, 45, 89}; WriteInts wi = new WriteInts(“mydata.dat”, myArr); ] 2.) Read Integers from a File – This time...
