Here is one of the crudest method

public class Reader {
      
      public static void main(String args[]) {
            try {
                  FileInputStream fip = new FileInputStream(new File("abc.txt"));
                  byte a;
                  int index = 0;
                  byte[] out = new byte[5000];
            
                  do
                  {
                        
                        a = (byte) fip.read();
                        
                        index++;
                        
                        out[index-1] = a;
                  }while(a != -1);
                  
                  String a1 = new String(out,0,index-1);
                  System.out.println(a1);
                  
            } catch (FileNotFoundException e) {
                  // TODO Auto-generated catch block
                  e.printStackTrace();
            } catch (IOException e) {
                  // TODO Auto-generated catch block
                  e.printStackTrace();
            }
      }

}
