reads in two integers and determines and prints if the first is a multiple of the second using the modulus operator. Is this correct algorithm below

public static void main(String[] args) {
int in = 10;
passMethod(in);

// print x to see if its value has changed
System.out.println("After invoking passMethod, in = " + in);
}
public static void passMethod(int p) {
p = 20;
}
}


calculates the squares and cubes of the numbers from 0 to 10
Did I do this Algorithm correct if anyone can understand it?

Step1: Input or variable declaration

Step2: //Output
System.out.printf( "number\tsquare\tcube\n");
System.out.printf( "%d\t%d\t%d\n", number , square, cube);

Step3: // Processing
number =number + 1;
square = number*number;
cube = number*number*number;

Step4: //Output
System.out.printf( "%d\t%d\t%d\n", number, square, cube);

Step5: Repeat Step 3
Step6: Repeat Step 4
Step7: Repeat Step 3
Step8: Repeat Step 4
Step9: Repeat Step 3
Step10: Repeat Step 4
Step11: Repeat Step 3
Step12: Repeat Step 4
Step13: Repeat Step 3
Step14: Repeat Step 4
STep15: Repeat Step 3
STep16: Repeat Step 4
STep17: Repeat Step 3
STep18: Repeat Step 4
STep19: Repeat Step 3
STep20: Repeat Step 4
STep21: Repeat Step 3
STep22: Repeat Step 4
Step23: Stop

Not exactly !
You should have something like this :

    int x = some value;
    int y = some value;
    int r = y % x;
    if (r == 0) {
        System.out.println(y + " is a multiple of " + x);
    }

For the second part, just use a for statement :

    for (int x = 0; x < 11; x++) {
       System.out.printf(""%d\t%d\t%d\n", x, (x*x), (x*x*x));
    }
