Feb 28, 2022 · The simplest approach to solve this problem is to iterate a loop over the range [0, N – 1], where N denotes the length of the string, using the variable i and print the value of str [i]. Example. Method 2: Using String.toCharArray () method. In this approach, we convert string to a character array using String.toCharArray () method.

Jan 21, 2021 · to print * according to the value i contains each time it loops. It basically creates a new char array of size i and replaces all the nulls , i.e.('\0'), with * of that char array, and then it converts the char array into one single string and prints it.

Jun 6, 2021 · Method 1: Using for loops. The simplest or rather we can say naive approach to solve this problem is to iterate using a for loop by using the variable ‘ i’ till the length of the string and then print the value of each character that is present in the string. Example. Time complexity is O (N) and space complexity is O (1) Method 2: Using iterators.

You can make use of a char[] array of given length to build a String, then replace each character with *: String repeatedStar = new String(new char[4]).replace('\0', '*'); Well, that would use a loop internally though.

Oct 30, 2015 · Use String[] lineValue; instead of String lineValue because only last line is assigned to this variable and int k = 0; while ((line = reader.readLine()) != null) { lineValue[k]=line; k++; }

Write a Java program to print characters in a string with an example. In the following example, we used for loop to iterate each and every character from start to end and print all the characters in the given string.

Java Code for this is as follows. System.out.println("Printing the string" + N + "times in a single line."); Using the repeat () method. Java11 has a method to do this very easily. We can use the repeat () method of org.apache.commons.lang3 package for this. The method can be used as my_string.repeat (n) my_string: Java 11. N: 4.

May 11, 2024 · In Java, there are several ways to iterate over the characters of a string, each with its own time and space complexity. The best method to use depends on the specific requirements of your program. We can use a simple for loop to iterate over the characters of a string.

In Java, you can print a character multiple times using a loop or by simply repeating the character using a string concatenation approach. Here are two common ways to achieve this: Using a Loop (for or while):

Mar 20, 2024 · In Java programming, when you need to display a string without automatically moving to the next line, you can employ the System.out.print () method. Unlike its counterpart println (), which automatically appends a newline character, print () …
