This game is like FizzBuzz but with different words as you can see.
I need to print the result of "Nardo" to output(System.out.println
) and to file, when called, at the same time.
I made 2 classes one for FizzBuzz game and the other to sent some text into the file. This one works correctly, but I don't know how to combine it with FizzBuzz Class.
I just called the class OutputToFile into the FizzBuzz, but I don't know how to continue.
1) First Class
public class BaroSello {
private OutputToFile outputfile = new OutputToFile();
for(int i=1; i<input; i++){
if ((i % 3 == 0 && i % 5 == 0))
System.out.println("BaroSello");
else if (i % 3 == 0)
System.out.println("Baro");
else if (i % 5 == 0)
System.out.println("Sello");
else if (i%7==0)
// here I need the output to file and to terminal
System.out.println("Nardo");
else
System.out.println(i);
}
}
2) Second Class
public class OutputToFile {
public static void main(String[] args) {
try {
PrintStream myconsole = new PrintStream(new File("/Users/xxx/Desktop/output.txt"));
System.setOut(myconsole);
myconsole.println("hello");
} catch (FileNotFoundException fx) {
System.out.println(fx);
}
}
}
The class below will split the calls you make to a 2 OutputStream's.
For your program, instead of creating a PrintStream from the file, first create a FileOutputStream. Then create a new SplitOutputStream from your FileOutputStream and System.out. With the SplitOutputStream, any single write you make will be written to both the FileOutputStream and System.out. By wrapping a PrintStream over the SplitOutputStream, you can now do println on the PrintStream, and the output will go to both the file and the System.out.
import java.io.*;
public class SplitOutputStream extends OutputStream{
public static void main(String[] args) throws Throwable{
SplitOutputStream split=new SplitOutputStream(
new FileOutputStream("c:\\text.txt"),
System.out
);
PrintStream splitPs=new PrintStream(split);
splitPs.println("some text");
splitPs.flush();
splitPs.close();
//or (not both)
PrintWriter splitPw=new PrintWriter(split);
splitPw.println("some text");
splitPw.flush();
splitPw.close();
}
OutputStream o1;
OutputStream o2;
public SplitOutputStream(OutputStream o1,OutputStream o2){
this.o1=o1;
this.o2=o2;
}
@Override public void write(int b) throws IOException{
o1.write(b);
o2.write(b);
}
@Override public void write(byte[] b,int off,int len) throws IOException{
o1.write(b,off,len);
o2.write(b,off,len);
}
@Override public void flush() throws IOException{
o1.flush();
o2.flush();
}
@Override public void close() throws IOException{
o1.close();
o2.close();
}
}
Or
PrintStream originalSysOut=System.out;
SplitOutputStream split=new SplitOutputStream(
new FileOutputStream("c:\\work\\text.txt"),
originalSysOut
);
PrintStream splitPs=new PrintStream(split,true);
System.setOut(splitPs);
System.out.println("some text");
The code above changes the System.out to output to your file plus the original System.out
