24000 at 5.5 for 5 years
If you take out a five-year loan for $24000 and the interest rate on the loan is 5.5 percent. The rate is $66,0000.
What is the interest rate?
The interest rate is the amount charged by a lender to a borrower and is expressed as a percentage of the principal—the amount loaned. If a lender employs the simple interest method, calculating loan interest is simple if you have the necessary information.
To calculate the total interest costs, you will need your principal loan amount, interest rate, and the total number of months or years you will repay the loan.
The simple interest formula would be $24000 x 5.5 x 5 = $66,0000 in interest.
Therefore, the simple interest formula would be $24000 x 5.5 x 5 = $66,0000 in interest.

void readData() throws IOException {
BufferedReader br = new BufferedReader(new InputStreamReader( new FileInputStream("file")));
// Read from the file
String data = br.readLine();
}
The code is presented as a non-compliant code example. For this assignment, identify 2 compliant solutions that can be utilized to ensure the protection of sensitive data.
Provide an explanation of factors that influence non-compliant code and specifically how your solutions are now compliant.
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.
