How to read arrays from user in java? [closed]

Question

What is the java equivalent of the following C code.

for(i = 0;i<n;i++)
scanf("%d",&a[i])

where i is a previously defined integer and a is an array

Answer 1

The scanner class is used, System.in is the standard input, but it can get other input streams:

Scanner scan = new Scanner(System.in);
for(i = 0;i<n;i++) {
    a[i] = scan.nextInt();
}

Anyway, this might cause you some problems if the user press enter between two numbers, so another approach will be:

Scanner scan = new Scanner(System.in);
for(i = 0;i<n;i++) {
    String token = scan.next();
    a[i] = Integer.parseInt(token);
}
