Taking inputs with BufferedReader in Java

Question

I have a bit of an annoying case here  wherein I am not able to take the input properly  I have always taken input via Scanner  and am not used to the BufferedReader      INPUT FORMAT    First line contains T  which is an integer representing the number of test cases  T cases follow  Each case consists of two lines   First line has the string S   The second line contains two integers M  P separated by a space      EXAMPLE  Input  2 AbcDef 1 2 abcabc 1 1     My code so far     public static void main  String   args  throws java lang Exception       BufferedReader inp   new BufferedReader  new InputStreamReader System in        int T  Integer parseInt inp readLine          for int i 0 i lt T i              String s  inp readLine            int   m  new int 2           m 0  inp read            m 1  inp read                Checking whether I am taking the inputs correctly         System out println s           System out println m 0            System out println m 1                When inputting to the above example shown  I get the following output   AbcDef 9 49 2 9 97

BufferedReader read reads  single character 0 to 65535  0x00-0xffff   from the stream  so it is not possible to read single integer from stream               String s  inp readLine                int   m  new int 2               String   s1   inp readLine   split                   m 0  Integer parseInt s1 0                m 1  Integer parseInt s1 1                    Checking whether I am taking the inputs correctly             System out println s               System out println m 0                System out println m 1      You can check also Scanner vs  BufferedReader

You can t read individual integers in a single line separately using BufferedReader as you do using Scannerclass   Although  you can do something like this in regard to your query    import java io    class Test      public static void main String args   throws IOException              BufferedReader br new BufferedReader new InputStreamReader System in           int t Integer parseInt br readLine            for int i 0 i lt t i                      String str br readLine             String num   br readLine   split                int num1 Integer parseInt num 0             int num2 Integer parseInt num 1               rest of your code                    I hope this will help you

The problem id because of inp read    method  Its return single character at a time and because you are storing it into int type of array so that is just storing ascii value of that   What you can do simply   for int i 0 i lt T i          String s  inp readLine        String   intValues   inp readLine   split           int   m  new int 2       m 0  Integer parseInt intValues 0        m 1  Integer parseInt intValues 1            Checking whether I am taking the inputs correctly     System out println s       System out println m 0        System out println m 1
