I am new to groovy. I have the following code where I want to print the Strings on the console, which doesn't work:
import java.io.FileWriter;
import java.util.Arrays;
import java.io.Writer;
import java.util.List;
//Default separator
char SEPARATOR = ',';
//get path of csv file (creates new one if its not exists)
String csvFile = "c:";
println "========================= csvFile";
println csvFile;
String[] params = {"hello"};
writeLine(params, SEPARATOR);
//function write line in csv
public void writeLine(String[] params, char separator)
{
boolean firstParam = true;
println params;
StringBuilder stringBuilder = new StringBuilder();
String param = "";
for (int i = 0; i < params.length; i++)
{
//get param
param = params[i];
println param;
//if the first param in the line, separator is not needed
if (!firstParam)
{
stringBuilder.append(separator);
}
//Add param to line
stringBuilder.append(param);
firstParam = false;
}
//prepare file to next line
stringBuilder.append("\n");
//add to file the line
println stringBuilder.toString();
}
It gives the following output:
in groovy to declare array you have to use square brackets:
String[] params = ["hello"]
btw whole code could be simplified to this:
String[] params = ["hello"]
def writeLine(params, separator=','){
println params.join(separator)
}
writeLine(params)
