I just required the upper one.

System.out.println(selectedproduct.get(j).getText().split("\\n"));

Answer 1

String.split() returns an array of values between each occurrence of the delimiter. The reason you're getting "garbage" values is because arrays use the default implementation of toString() . To print the full array, you can use Arrays.toString() :

System.out.println(Arrays.toString(selectedproduct.get(j).getText().split("\\n")));

If you only want the first line, just print the first element of the returned array:

System.out.println(selectedproduct.get(j).getText().split("\\n")[0]);

Answer 2

The .split() would create an array of strings so to get teh first part of splitted array use the index as you print.

System.out.println(selectedproduct.get(j).getText().split("\\n")[0]); //index of upper line for you

Also in some cases you might want to use \\r\\n for platform specific carriage return -

System.out.println(selectedproduct.get(j).getText().split("\\r\\n")[0]);
