you can use a Scanner to read from input :
Scanner scanner = new Scanner(System.in);
char c = scanner.next().charAt(0); //charAt() method returns the character at the specified index in a string. The index of the first character is 0, the second character is 1, and so on.

What’s the best way to store multiple string inputs in Java for later use?
When handling multiple string inputs, especially if the count isn’t fixed, use dynamic data structures like ArrayList. After reading strings using scanner.nextLine() or splitting a line into tokens, add each entry to the list. This allows you to easily perform operations like searching, filtering, or mapping over the input later in the program.

How do you handle exceptions or errors while taking multiple string inputs using Scanner?
Scanner input operations can throw exceptions such as NoSuchElementException or IllegalStateException if input is prematurely closed or unavailable. Although strings rarely cause format issues like numbers do, you should still handle unexpected inputs or stream closure gracefully. Using try-catch blocks around input reading logic ensures your program can inform users of errors and request re-entry instead of crashing. This practice is critical in interactive applications like user registration or command-line tools, where reliability improves user trust and reduces debugging time.

How can I optimize Scanner usage when taking multiple string inputs in large-scale applications?
In large-scale or performance-sensitive applications, the scanner may become a bottleneck due to internal parsing and buffering. Alternatives like BufferedReader combined with String.split() offer faster input reading for bulk data. However, Scanner’s convenience for tokenizing inputs remains valuable for simpler interactive programs. To optimize Scanner usage, you can minimize calls to input methods, reuse Scanner objects, and avoid unnecessary parsing steps. Also, consider closing Scanner streams properly to free resources. These practices are critical when building scalable command-line uti

If you separate your input using whitespace and then press enter like this:
2 3
You can use nextInt() normally:
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
a = in.nextInt();
b = in.nextInt();
}
a will contain 2 and b will contain 3.
If you need to, you can place both nextInt() calls inside a loop, so you can read multiple lines:
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
int numLines = in.nextInt();
int a, b;
for (int i = 0; i < numLines; i++) {
a = in.nextInt();
b = in.nextInt();
System.out.println(a + ", " + b);
}
}

To take multiple inputs from the user from the same input line, you can ask the user to seperate the input with a comma or a white space.
In case of a white space, Anderson Vieira's answer gives the correct idea. You can use 2 successive nextInt() statements as in
System.out.println("Enter 2 nos.");
int a = sc.nextInt();
int b = sc.nextInt();
Also, you can specifically ask the user to seperate two nos. with a comma, take the input as a String and then seperate the two nos. using Integer.parseInt() command.
System.out.println("Enter 2 nos. seperated with a comma(,) or a semicolon(;)");
String S = sc.nextLine();
String nos[] = S.split("[, ;]");
int a = Integer.parseInt(nos[0]);
int b = Integer.parseInt(nos[1]);
You can ofcourse use any other character to seperate the nos.
