// i need help print 100 char and 100 num tem per line.i try try but no success.thks in adv

public class C5E23{
public static void main(String[] args){

int num;

for(char s = 0; s < 100; ++s) {
//for(int perLine = 0; perLine <= 10; ++perLine)
char ch = getRandomCharacter(s);
System.out.print(ch);
}
{
for(int i = 0; i < 100; ++i)
num = (int) getRandomDigital(i);
System.out.print(num);
}


}//end main

thnks Hardwire for big help.the program is printing rite but i think it was suppost to print ten line of tem which will be hundred of num and hundred of char.also wht are those: a = a/97 z = z/122 '0' = 0/48 '9' = 9/97

thnks in adv

also wht are those: a = a/97
char value / char value cast to an int value
Just to see what you're working with.
