I don't know why posts are cut but aftr y=0
for(int y=0; y<n; y++){
for(int z=0; z<n ;z++){
System.out.printf("%2d",a[y][z]); System.out.print(" ");
}
System.out.println();
}

}

joined ur post WOW nice to see that i am not the only one who is awake till 1:30 today

Best of luck

I just made a prog. to generate truth table for three variable expression of type a.b+b.c+c.a+a.b.c+ .....
(single variable not allowed in expression)(input should be in ablove format only)

I just started studying at 12:20. Didn't want to get into this situation but got into it nonethe less. Smile

Note the System.out.printf in my program. The matrix that is printed is properly formatted.Anagrams via Recursion (though this will not come):</br>import java.io.*;
public class Anagrams {
public static void main(String args[])throws IOException {
BufferedReader in= new BufferedReader(new InputStreamReader(System.in));
System.out.print("Enter a word:");
String word=in.readLine();
System.out.println("The anagrams of the word are:");
printAnagrams("",word);
}
public static void printAnagrams(String prefix,String word){
if(word.length()<=1) System.out.println(prefix+word);
else {
for (int i=0;i<word.length();i++){
String current=word.substring(i,i+1);
String before=word.substring(0,i);
String after=word.substring(i+1);
printAnagrams(prefix+current,before+after);
}
}
}
}
