StringBuilder are not workin in my eclipse

#1

StringBuilder Methods are not working in classes in packages made by me but working fine in default packages.

#2

That should not happen, can you tell me what compilation error the ide is showing? Are you sure you have initialized it correctly?

  	StringBuilder s = new StringBuilder();
#3

Whichever method of string builder I am using it says its not defined. Its happening not in those classes which are under packages not in default packages.
For eg :- I use sb.length(). for this method error is lenth() is undefined for type StringBuilder.

#4

Can you please share your complete code for which you are trying to use stringbuilder? There is probably some minor error in syntax

#5

package section5;

public class StringBuilderDemo {

public static void main(String[] args) {
	StringBuilder sb = new StringBuilder();
	
	int a = sb.length();
	System.out.println(a);

}

}

Your code seems correct and is working for me in my eclipse ide. I have transferred your doubt to a mentor, they will help you with it.

#7

I added (import java.lang.StringBuilder;) to the code, now its working fine.

#8

Okay, that’s great. Though it usually works without importing as well.
