// 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
public static char getRandomCharacter(char ch1, char ch2){
return (char) (ch1 + Math.randon() * (ch2 - ch1 + 1));
}
public static char getRandomDigitalCharacter(){

return getRandomCharacter('0' , '9');
}







}//end class

Code:

    public static void main(String[] args) {
        int limit = 10;
        char a = 'a', z = 'z';
        System.out.printf("a = %s/%d  z = %s/%d  " +
                          "'0' = %s/%d  '9' = %s/%d%n",
                           a, (int)a, z, (int)z,
                          '0', (int)'0', '9', (int)'9');
        System.out.println("RandomCharacter: ");
        for(char s = 0; s < limit; ++s) {
            char ch = getRandomCharacter(a, z);
            System.out.print(ch);
            if(s < limit-1)
                System.out.print(", ");
        }
        System.out.println("\nRandomDigitalCharacter: ");
        for(int i = 0; i < limit; ++i) {
            int num = (int) getRandomDigitalCharacter();
            System.out.print(num);
            if(i < limit-1)
                System.out.print(", ");
        }
    }

    public static char getRandomCharacter(char ch1, char ch2){
        return (char) (ch1 + Math.random() * (ch2 - ch1 + 1));
    }

    public static char getRandomDigitalCharacter(){

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.
