I just wanted to read a file line by line. This was meant to be simple, but i just can't get it right! String fileName = "C:/Users/Diogo/Desktop/Krs_Grafo/Graph.txt"; FileReader file = new FileReader(fileName); BufferedReader inputStream = new BufferedReader(file); System.out.println(inputStream.readLine()); i keep getting the error: Exception in thread "main" java.io.FileNotFoundException: C:\Users\Diogo\Desktop\Krs_Grafo\Graph.txt (O sistema não pode encontrar o arquivo especificado) at java.io.FileInputStream.open(Native Method) at java.io.FileInputStream.<init>(FileInputStream.java:120) at
