java - How to print out from a nested Array List -


this question has answer here:

this code far :

arraylist<string[]> data = timetable.gettimetabledata();      (int = 0; < data.size(); i++){          (int j = 0; j < data.get(i).length; j++){             printwriter.print("value " + data + "\n");          }         //printwriter.print("length " + data.get(j). + "\n");     }

i having issue print out values, been looking @ ways , that's why posting here. hold in arraylist values coming database. expecting 14 values altogether. seeing 14 values in current out put can see weird characters.

this output :

value [[ljava.lang.string;@15ad30e, [ljava.lang.string;@2403d547] value [[ljava.lang.string;@15ad30e, [ljava.lang.string;@2403d547] value [[ljava.lang.string;@15ad30e, [ljava.lang.string;@2403d547] value [[ljava.lang.string;@15ad30e, [ljava.lang.string;@2403d547] value [[ljava.lang.string;@15ad30e, [ljava.lang.string;@2403d547] value [[ljava.lang.string;@15ad30e, [ljava.lang.string;@2403d547] value [[ljava.lang.string;@15ad30e, [ljava.lang.string;@2403d547] value [[ljava.lang.string;@15ad30e, [ljava.lang.string;@2403d547] value [[ljava.lang.string;@15ad30e, [ljava.lang.string;@2403d547] value [[ljava.lang.string;@15ad30e, [ljava.lang.string;@2403d547] value [[ljava.lang.string;@15ad30e, [ljava.lang.string;@2403d547] value [[ljava.lang.string;@15ad30e, [ljava.lang.string;@2403d547] value [[ljava.lang.string;@15ad30e, [ljava.lang.string;@2403d547] value [[ljava.lang.string;@15ad30e, [ljava.lang.string;@2403d547]

please, can guide or output correct? thank :)

just need change

printwriter.print("value " + data + "\n");

for

printwriter.print("value " + data.get(i)[j] + "\n");

thats because dat.get(i) array of strings. , want access j element of array.
