如何使用扫描仪读取带有斜杠的 java 中的输入？

Question

I want to ask about how to get the value from user input input in java with scanner.

eg the input is: 1000/2

i want to get like this a = 1000 and b = 2.

thank you in advance.

Answer 1

Try this.

Reader reader = new StringReader("1000/2");
try (Scanner in = new Scanner(reader).useDelimiter("/")) {
    int a = in.nextInt();
    int b = in.nextInt();
    System.out.println("a = " + a + ", b = " + b);
}

output

a = 1000, b = 2

Answer 2

Try This.

String s[] = scannerObject.next().split("/"); // split the input at once
int a = Integer.parseInt(s[0]); // convert string to integer
int b = Integer.parseInt(s[1]); 

Answer 3

You could use the splicing method. a = [YOUR VAR].substring([YOUR SPLICING POS])
