The usage of try-catch statements in the aforementioned code makes it compliant, as opposed to just throwing exceptions. Since all of the errors are fixed, the program becomes more compliant.
What is the purpose of Java?The main language for creating Android mobile applications is Java. In actuality, Java is used to create the Android operating system. While Kotlin has lately emerged as a Java-free alternative for Android development, it still makes use of the Java Platform and can communicate with Java code.
Main.java:
import java.io.*;
public class Main {
public static void main(String[] args) {
BufferedReader br = null;
try {
String data;
br = new BufferedReader(new FileReader("file.txt"));
while ((data = br.readLine()) != null) {
System.out.println(data);
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
if (br != null)
br.close();
} catch (IOException ex) {
ex.printStackTrace();
}
}
}
}
Output:
Main.java
import java.io.*;
public class Main {
private static final String FNAME = "file.txt";
public static void main(String[] args) {
try (BufferedReader b = new BufferedReader(new FileReader(FNAME))) {
String data;
while ((data = b.readLine()) != null) {
System.out.println(data);
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
The application will determine whether the file is present and whether it contains any data. Never will the application issue any warnings or compile-time problems. Additionally, we used a finally statement to guarantee that the program was running correctly.
Similar to the first option, the second solution uses the try-catch method directly to read the file without any additional components, keeping the program short and organized. I will advise utilizing the first application because it's much more compliant and because all the work put into it has made it more effective and simple to use.
