String Reversal

[Kumar_Kumar]

Hi All,

I have a requirement where I need to reverse a string. For eg: 12345 should be changed to 54321. Does anyone of you know if we have any util that I can use?

Please let me know. Thanks for your time.

Hi Kumar,

I am currently thinking of 2 approaches:

1. Using regular expressions if possible. (I am not sure about that)
2. convert the string into byte arry, reverse the byte array and convert it back to a string

Most likely option 2 will result in a small java service.

Eventually some other members have further ideas on this.

Regards,
Holger

write down java service for the same. I don’t think built-in service exist for this.

Thanks,

OOTB there is no services provided in WmPubic package however you can use the Java API. There are many ways in doing this however below is one of the core code snippet:

import java.io.;
import java.util.;

public class reverseString {
public static void main(String args) {
String input=“AliveisAwesome”;
StringBuilder input1 = new StringBuilder();
input1.append(input);
input1=input1.reverse();
for (int i=0;i<input1.length();i++)
System.out.print(input1.charAt(i));
}}>

	// pipeline
	IDataCursor pipelineCursor_1 = pipeline.getCursor();
	
	IDataUtil.put( pipelineCursor_1, "output",input1 );
			pipelineCursor_1.destroy();
	
			 
			input1.append(input); 
			input1=input1.reverse();
