Review Activity
1. Given the following lines of code, write a loop to read in the file word by word:
String word;
int count = 0;
File file = new File("in.txt");
Scanner input = new Scanner(file);
while( ) {
word =
count++;
System.out.println("Word " + count + ": " + word);
}
2. Given the following lines of code, write a loop to read in the file line by line:
String line;
int count = 0;
File file = new File("in.txt");
Scanner input = new Scanner(file);
while( ) {
line =
count++;
System.out.println("Line " + count + ": " + line);
}
3. Write a method to print
an array of Strings to the console, with each element separated on its
own line. The method should be named printArray. It takes an array of
Strings as a parameter. It returns nothing.
4. Write the below method:
/**
* Given an array of ints, return true if 10 appears as
* either the first or last element in the array. The array will be size 1 or more.
* first10Last([1, 2, 10]) → true
* first10Last([10, 1, 2, 3]) → true
* first10Last([13, 10, 1, 2, 3]) → false
* @param data the array of integer values
* @return whether or not 10 appears as the first or last element
