Answer:
92
Explanation:
int index = 1 + 6 % 3;
Modulo is calculated before adding, so as first you need to calc 6 % 3, result is 0.
int index = 1 + 0 = 1;
Indexes in arrays starts from 0, ends in length - 1. So first element in the array has 0 as index, second element has 1 as idnex, etc. Your index = 1, so value of the second element in the grades will be your result. Finally, the answer is 92.
Answer:
The code above tries to read a file using the scanner class in java programming language.
But it was done properly.
First, the scanner class library is not imported to the program.
Second,the syntax used in this program is an invalid way of reading a file in java programming language using the scanner class.
Lastly, "String s = file.nextLine();" is not a proper way of reading each line
To correct this problem; use the following code;
import java.util.Scanner;
import java.io.File;
import java.io.FileNotFoundException;
public class ReadFileWithScanner {
try
{
public static void main(String args[]) throws FileNotFoundException {
File text = new File("data.txt");
Scanner file = new Scanner(text);
int lines = 1;
while(file.hasNextLine()){
String line = filw.nextLine();
System.out.println("line " + lines + " :" + line);
lines++;
}
catch (ArithmeticException ae)
{
System.out.println(ae.getMessage());
}
}
}
