basic reading input from user in java -

i want read character , store char[] array , here method called getaline

public static int getaline(char message[], int maxlength) {      int index = 0;      while (message[index] != '\n')      {          message[index] = fgetc(system.out);          index++;      }      index++; } 

and fgetc method:

public static int fgetc(inputstream stream) 

and method should returns character input stream.

but keep getting error message when compile:

error: possible loss of precision

message[index] = fgetc(system.in);                        ^ required: char  found:    int 

what should put inside fgetc can collect input user??

your code expecting char, return int here:

public static int fgetc(inputstream stream) //            ↑ tells method return int 

you can

• change method signature return char.

  public static char fgetc(inputstream stream) //            ↑ tells method return char 

• cast returned value char

  casting conversion (§5.5) converts type of expression type explicitly specified cast operator (§15.16).

  message[index] = (char) fgetc(system.in); //               ↑ cast returning value char
