doubt in string.split method

[vicky chauhan]

Hello guys,

I have following data:

1||1||Abdul-Jabbar||Karim||1996||1974

I want to delimit the tokens.

Here the delimiter being "||".

My delimiter setter is:

public void setDelimiter(String delimiter) 
{     
    char[] c = delimiter.toCharArray();    
    this.delimiter = "\""+"\\"+c[0]+"\\"+c[1]+"\"";     
    System.out.println("Delimiter string is: "+this.delimiter); 
} 

However, String[] tokens = line.split(delimiter); is not giving required result.

Please help!!

Nik

this.delimiter = "\""+"\\"+c[0]+"\\"+c[1]+"\"";

Why would you start with "\"" and end with "\"" ?
and what if your delimiter doesn't need escape character?

can you explain what you are trying to do in setDelimiter method?

Bit tricky. But still, it should not take much time to resolve.

Assuming that you came here for advise on the possible delimeters, let me know if the below code did helped you.

String data = "1||1||Abdul-Jabbar||Karim||1996||1974";
String delimeter = "(?:\\b[\\|]+[\\|]+)";
		
String[] dataArr = data.split(delimeter);
		
for(int i=0;i<dataArr.length;i++)
System.out.println("Value "+(i+1)+": "+dataArr[i]);

System.out.println("Value "+(i+1)+": "+dataArr[i]);

Here is how I did it:

String delimiter = "||";
Pattern pattern = Pattern.compile(Pattern.quote(delimiter));
String[] tokens = pattern.split(line);

This worked perfectly... and is more efficient too!! Thanks to Ray!!
