Java - How to print a char a certain number of times?

To print a character a certain number of times in Java, you can use a loop, such as a for loop or a while loop, to repeat the printing process. Here's an example using a for loop:

public class PrintCharMultipleTimes { public static void main(String[] args) { char characterToPrint = '*'; int numberOfTimes = 5; // Using a for loop to print the character multiple times for (int i = 0; i < numberOfTimes; i++) { System.out.print(characterToPrint); } // Add a newline after printing the characters System.out.println(); } }

In this example:

  • characterToPrint represents the character you want to print.
  • numberOfTimes represents the number of times you want to print the character.
  • The for loop is used to iterate from 0 to numberOfTimes - 1, printing the character in each iteration.
  • After the loop, a newline is added to move to the next line.

You can customize the characterToPrint and numberOfTimes variables according to your requirements.

If you want to encapsulate this behavior in a method, you can create a method like the following:

public class PrintCharMultipleTimes { public static void main(String[] args) { char characterToPrint = '*'; int numberOfTimes = 5; printCharMultipleTimes(characterToPrint, numberOfTimes); } public static void printCharMultipleTimes(char characterToPrint, int numberOfTimes) { for (int i = 0; i < numberOfTimes; i++) { System.out.print(characterToPrint); } System.out.println(); // Add a newline after printing the characters } }

This way, you can reuse the printCharMultipleTimes method throughout your code. Adjust the parameters as needed.

Examples

  1. Java: Print a character multiple times using loops

    // Using a for loop int count = 5; char ch = 'A'; for (int i = 0; i < count; i++) { System.out.print(ch); }

  2. How to repeat a character in Java without a loop?

    // Using String's repeat method (Java 11 and later) int count = 3; char ch = 'X'; String repeated = String.valueOf(ch).repeat(count); System.out.print(repeated);

  3. Java code to print a character n times using StringBuilder

    // Using StringBuilder int count = 4; char ch = 'B'; StringBuilder result = new StringBuilder(); for (int i = 0; i < count; i++) { result.append(ch); } System.out.print(result.toString());

  4. Print a character a specific number of times in Java with Arrays

    // Using Arrays.fill int count = 6; char ch = 'Z'; char[] charArray = new char[count]; Arrays.fill(charArray, ch); System.out.print(charArray);

  5. Java: Print a character n times using recursion

    // Using recursion int count = 7; char ch = 'C'; printCharNtimes(ch, count); // Recursive method private static void printCharNtimes(char ch, int count) { if (count > 0) { System.out.print(ch); printCharNtimes(ch, count - 1); } }

  6. How to print a character certain times using Apache Commons Lang

    // Using StringUtils from Apache Commons Lang int count = 3; char ch = 'D'; String repeated = StringUtils.repeat(ch, count); System.out.print(repeated);

  7. Print a character n times in Java with IntStream

    // Using IntStream int count = 8; char ch = 'E'; IntStream.range(0, count).forEach(i -> System.out.print(ch));

  8. Java code to print a character n times with String concatenation

    // Using String concatenation int count = 5; char ch = 'F'; String result = new String(new char[count]).replace('\0', ch); System.out.print(result);

  9. How to print a character a certain number of times with Collections.nCopies

    // Using Collections.nCopies int count = 4; char ch = 'G'; List<Character> charList = Collections.nCopies(count, ch); charList.forEach(System.out::print);

  10. Print a character n times in Java using printf

    // Using printf int count = 6; char ch = 'H'; System.out.printf("%0" + count + "d", 0).replace('0', ch);
