COMPLETE QUESTION
I. public class Test {
public static void main(String[] args){
System.out.println("Welcome to Java!");
}
}
II. public class Test { public static void main(String[] args) {System.out.println("Welcome to Java!");}}
Answer:
Both codes will compile and run and display Welcome to Java, but the code in II has a better style than I
Explanation:
When written codes, paying attention to proper coding styles and efficient memory management enables us to create programs that are highly efficient, coding styles refer to proper indentions and avoiding too lenghty lines of code (as is in code I), adding approprite comments etc.
Answer:
public class array{
public static void main(String []args){
int[] array = {2,4,7,1,9};
int num_vals = array.length;
for(int i=0;i<num_vals;i++){
System.out.println(array[i] + " ");
}
for(int i=num_vals-1;i>=0;i--){
System.out.println(array[i] + " ");
}
}
}
Explanation:
First create the class in the java programming.
Then create the main function and declare the array with values.
Store the size of array in num_vals variable by using the function array.length.
create a for loop to iterate the each element in the array and then print on the screen with spaces and newline.
it traverse the loop from first to last.
Then, again create the for loop to iterate the each element in the array and then print on the screen with spaces and newline but the traversing start from last to first.
