Array ticket[x][2] is String, and ticket[x][1] is String too. The array ticket[x][1] is {"1", "2", "3"}. How to fill ticket[x][2]? I want in integer. In my code is still error using Integer.parseInt().
String[][] ticket = new String[8][3];
for (int x = 0; x < limit; x++) {
if(ticket[x][0].equals("festival")) {
ticket[x][2] = Integer.parseInt(ticket[x][1]) * 250000;
}
}
Because ticket[x][2] is a String (you are trying to assign an int).
ticket[x][2] = "" + (Integer.parseInt(ticket[x][1]) * 250000);
or
ticket[x][2] = String.valueOf(Integer.parseInt(ticket[x][1]) * 250000);
public class StringToIntegerArray {
public static void main(String args[]) {
String [] str = {"123", "345", "437", "894"};
int size = str.length;
int [] arr = new int [size];
for(int i=0; i<size; i++) {
arr[i] = Integer.parseInt(str[i]);
}
System.out.println(Arrays.toString(arr));
}
}
Result:
[123, 345, 437, 894]
