Simple For Loop
The below command line program demonstrates how to write a for loop to repeat a block of code for user specified number of times.
Main.java
package ceccs;
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
System.out.println("Random number generator: How many?");
Scanner scan = new Scanner(System.in);
int numValues = scan.nextInt();
for(int i = 0; i < numValues; i++){
double randNo = Math.random();
String output = String.format("Value number %d: %.2f", i+1, randNo);
System.out.println(output);
}
}
}
