5 Reasons to Master String if you are a Java Developer

5 Reasons you should master String Processing if you are a Java Developer? java.lang.String class in Java library is one of the most important class which we make use in our project development. You won’t be able to develop a single Java Project without making use of String.

1. You use a lot of String in your Project Development

• Any project you work upon will have tons of String generated. Almost every third line of code you write in your Java Code will be using String properly. Every Time you try to print details about an object in System.out.println() or out.println() in JSP make use of String.
• There are lot of options available to work with String and knowing them handy is something which will be recommended for a Java Developer. Having knowledge about convenience classes which works with String like CharSequence and StringBuilder or StringBuffer also helps.

2. Many API’s internally use String for Inter connectivity among st.

• JSON and XML are one of the major API’s which are used for connecting application working on other languages or even in same language with each other. String is the only way through which application communicate amongst. Data entered on Facebook through web get reflected on Android App version of Facebook, hence they internally make use of String to pass the data through JSON which uses String internally.

3. Databases return your data in String

• RDBMS when connected with Java Application returns the values in String format. Data in backend could be in any format, let say you fetch id from a table which is format of AX0099 and now you want to convert that to AX0100, you have got to make use of String in following way

· class NextIdGeneration { public static void main(String[] args) { String id="AX00099"; id=id.replace("AX",""); int x=Integer.parseInt(id); x=x+1; String nextId=""; if(x>=1&&x=10&&x=100&&x=1000&&x=10000&&x
