Question
Write a static method named printStrings that takes as a parameter a Scanner holding a String that contains a sequence of integer/string pairs and that prints to System.out one line of output for each pair with the given String repeated the given number of times. For example if the Scanner contains the following data:
6 fun. 3 hello 10 <> 2 25 4 wow!
your method should produce the following output:
fun.fun.fun.fun.fun.fun.
hellohellohello
<><><><><><><><><><>
2525
wow!wow!wow!wow!
Notice that there is one line of output for each integer/string pair. The first line has 6 occurrences of "fun.", the second line has 3 occurrences of "hello", the third line has 10 occurrences of "<>", the fourth line has 2 occurrences of "25" the fifth line has 4 occurrences of "wow!". Notice that there are no extra spaces included in the output. You are to exactly reproduce the format of this sample output. You may assume that the input values always come in pairs with an integer followed by a String (which itself could be numeric, such as "25" above). If the Scanner is empty (no integer/string pairs), your method should produce no output.
import java.util.*;
public class PrintStrings {
public static void main(String[] args) {
String input = "6 fun. 3 hello 10 <> 2 25 4 wow!";
Scanner stringParser = new Scanner(input);
printStrings(stringParser);
}
// your code here
Explanation / Answer
PrintStrings.java
import java.util.*;
public class PrintStrings {
public static void main(String[] args) {
String input = "6 fun. 3 hello 10 <> 2 25 4 wow!";
Scanner stringParser = new Scanner(input);
printStrings(stringParser);
}
// your code here
public static void printStrings(Scanner scan) {
while(scan.hasNext()) {
int n = Integer.parseInt(scan.next());
String s = scan.next();
for(int i=0;i<n;i++){
System.out.print(s);
}
System.out.println();
}
}
}
Ouput:
fun.fun.fun.fun.fun.fun.
hellohellohello
<><><><><><><><><><>
2525
wow!wow!wow!wow!
