How to convert string to int when using BufferedReader?
System.out.println("input a number"); int n=Integer.parseInt(br.readLine(system.in));
But for some reason, it doesn't work
The error message says:
No suitable method (Java. Io. InputStream) was found for readLine
It also says br ReadLine not applicable
Solution
Inputstreamreader needs to be specified in the BufferedReader constructor Inputstreamreader converts a byte stream to a character stream As others have mentioned, you can recognize the exceptions that can be thrown from this code, such as IOException and numberformatexception
BufferedReader br = new BufferedReader(new InputStreamReader(system.in)); System.out.println("input a number"); int n = Integer.parseInt(br.readLine());
