Lily :
I want to store the string into CSV file using the following code but empty CSV is being generated.
Code
try {
PrintWriter writer = new PrintWriter(new File("test.csv"));
StringBuilder sb = new StringBuilder();
String str ="1 cup, honey, 2 tablespoons ,canola" ;
sb.append(str);
writer.write(String.valueOf(sb));
} catch (FileNotFoundException e) {
System.out.println(e.getMessage());
}
Expected Output :
The data should show like this in CSV file.
1 cup
honey
2 tablespoons
canola
How I could get expected results.?
JAMSHAID :
String str ="1 cup, honey, 2 tablespoons ,canola" ;
This keeps the data in a single line and every comma takes the data to new column as per the rules of CSV file. You need to append a new line in your data to keep your data to new line after every comma. This can be done through this.
try (PrintWriter writer = new PrintWriter(new File("test.csv"))) {
StringBuilder sb = new StringBuilder();
String str = "1 cup, honey, 2 tablespoons ,canola";
String []splitted_str=str.split(",");
for (String string : splitted_str) {
sb.append(string).append("\n"); //this will add a new line after every value separated by comma.
}
writer.write(sb.toString());
System.out.println("done!");
} catch (FileNotFoundException e) {
System.out.println(e.getMessage());
}
