How to Multiply Strings in Java to Repeat Sequences

Java String Multiplication

How about this??

System.out.println(String.format("%10s", "").replace(' ', '*'));

This gives me output as **********.

I believe this is what you want...

Update 1

int yournumber = 10;
System.out.println(String.format("%" + yournumber + "s","*").replace(' ', '*'));

Good Luck!!!

Simple way to repeat a string

String::repeat

". ".repeat(7)  // Seven period-with-space pairs: . . . . . . . 

New in Java 11 is the method String::repeat that does exactly what you asked for:

String str = "abc";
String repeated = str.repeat(3);
repeated.equals("abcabcabc");

Its Javadoc says:

/**
 * Returns a string whose value is the concatenation of this
 * string repeated {@code count} times.
 * <p>
 * If this string is empty or count is zero then the empty
 * string is returned.
 *
 * @param count number of times to repeat
 *
 * @return A string composed of this string repeated
 * {@code count} times or the empty string if this
 * string is empty or count is zero
 *
 * @throws IllegalArgumentException if the {@code count} is
 * negative.
 *
 * @since 11

Print a String 'X' Times (No Loop)

You can use recursion like this

private void printStar(int n){
    if(n > 0){
        System.out.print("*");
        printStar(n-1);
    }
}

And call the method like this initially - printStar(4);
