Java stop reading after empty line

Question

I\'m doing an school exercise and I can\'t figure how to do one thing. For what I\'ve read, Scanner is not the best way but since the teacher only uses Scanner this must be

Answer 1

 while (!sc.nextLine().equals("")){
        text[i] = sc.nextLine();
        i++;        
 }

This reads two lines from your input: one which it compares to the empty string, then another to actually store in the array. You want to put the line in a variable so that you're checking and dealing with the same String in both cases:

while(true) {
    String nextLine = sc.nextLine();
    if ( nextLine.equals("") ) {
       break;
    }
    text[i] = nextLine;
    i++;
}

Answer 2

The code below will automatically stop when you try to input more than 10 strings without prompt an OutBoundException.

String[] text = new String[10]
Scanner sc = new Scanner(System.in);
for (int i = 0; i < 10; i++){ //continous until 10 strings have been input. 
    System.out.println("Please insert text:");
    string s = sc.nextLine();
    if (s.equals("")) break; //if input is a empty line, stop it
    text[i] = s;
}

Answer 3

Here's the typical readline idiom, applied to your code:

String[] text = new String[11]
Scanner sc = new Scanner(System.in);
int i = 0;
String line;
System.out.println("Please insert text:");
while (!(line = sc.nextLine()).equals("")){
    text[i] = line;
    i++;        
}
