To remove newline, space and tab characters from a string, replace them with empty as shown below.replaceAll("[\t ]", "");Above, the new line, tab, and space will get replaced with empty, since we have used replaceAll()The following is the complete example.Example Live Demopublic class Demo {    public static void main(String[] args) {       String originalStr = "Demo\tText";       System.out.println("Original String with tabs, spaces and newline: "+originalStr);       originalStr = originalStr.replaceAll("[\t ]", "");       System.out.println("String after removing tabs, spaces and new line: "+originalStr);    } }OutputOriginal String with tabs, spaces and newline: Demo Text ...

The MMMM format for months is like entire month name: January, February, March, etc. We will use it like this.SimpleDateFormat("MMM");Let us see an example.// displaying month in MMMM format SimpleDateFormat simpleformat = new SimpleDateFormat("MMMM"); String strMonth= simpleformat.format(new Date()); System.out.println("Month in MMMM format = "+strMonth);Above, we have used the SimpleDateFormat class, therefore the following package is imported.import java.text.SimpleDateFormat;The following is an example.Example Live Demoimport java.text.Format; import java.text.SimpleDateFormat; import java.util.Date; import java.util.Calendar; public class Demo {    public static void main(String[] args) throws Exception {       // displaying current date and time       Calendar cal = Calendar.getInstance();     ...

The MMM format for months is the short name i.e. Jan, Feb, Mar, Apr, etc. Here, we will use the following.SimpleDateFormat("MMM");Let us see an example.// displaying month in MMM format SimpleDateFormat simpleformat = new SimpleDateFormat("MMM"); String strMonth= simpleformat.format(new Date()); System.out.println("Month in MMM format = "+strMonth);Above, we have used the SimpleDateFormat class, therefore the following package is imported.import java.text.SimpleDateFormat;The following is an example.Example Live Demoimport java.text.Format; import java.text.SimpleDateFormat; import java.util.Date; import java.util.Calendar; public class Demo {    public static void main(String[] args) throws Exception {       // displaying current date and time       Calendar cal = Calendar.getInstance();   ...

The following is our string.String str = "Jack";Now take a StringBuilder object.StringBuilder strBuilder = new StringBuilder();Perform left padding and extend the string length to 20. The string that will be padded comes on the left.while (strBuilder.length() + str.length() < 20) { strBuilder.append("demo"); }The following is an example wherein we have left padded a string with another string “demo”Example Live Demopublic class Demo {    public static void main(String[] args) {       String str = "Jack";       StringBuilder strBuilder = new StringBuilder();       // left padding with a string       while (strBuilder.length() + str.length() ...

Strings have no newlines. We can form them into two lines by concatenating a newline string. Use System lineSeparator to get a platform-dependent newline string.The following is an example.Example Live Demopublic class Demo {    public static void main(String[] args) {       String str = "one" + System.lineSeparator() + "two";       System.out.println(str);    } }Outputone twoLet us see another example. On Linux based system, the program will work correctly.Example Live Demopublic class Demo {    public static void main(String[] args) {       String str = System.lineSeparator();       System.out.println((int) str.charAt(0));    } }Output10

To format a string, use the String.format() method in Java. The following is an example that formats a string %s.Example Live Demopublic class Demo {    public static void main(String []args) {       String str = String.format("%s %s", "demo", "text");       System.out.print("String: "+str);    } }OutputString: demo textLeft pad a stringTo left pad a string, use the String.format and set the spaces.String.format("|%20s|", "demotext")If you add 30 above, it will display the first string after 30 spaces from the beginning.String.format("|%30s|", "demotext")The following is an example.Example Live Demopublic class Demo {    public static void main(String []args) {     ...

To left pad a string, use the String.format and set the spaces.String.format("|%20s|", "demotext")If you add 30 above, it will display the first string after 30 spaces from the beginning.String.format("|%30s|", "demotext")Example Live Demopublic class Demo {    public static void main(String []args) {       System.out.print(String.format("|%20s|", "demotext"));       System.out.println("Left padded!");    } }Output| demotext|Left padded

To right pad a string, use the String.format and set the spaces.String.format("%1$-" + 20 + "s", "demotext"));If you add 30 above, it will display the next string after 30 spaces from the beginning.String.format("%1$-" + 30 + "s", "demotext")The following is an example.Example Live Demopublic class Demo {    public static void main(String []args){       System.out.print(String.format("%1$-" + 20 + "s", "demotext"));       System.out.println("Right padded!");    } }Outputdemotext Right padded!

In this article, we will learn how to format strings into a table using Java. Java's System.out.format() method is a convenient way to display formatted output. We will define a string format that specifies column widths to ensure uniform spacing, allowing us to create a neat table layout. By using this approach, we can display multiple rows of string data in a structured and readable format without manually adjusting spaces for each entry.
