QUESTTON 11
There are five syntax errors in the following java program. Explain them by mentioning the line number with
each error.
public class
public static void main (String [] args) {
{
double a = 9;
4
double b = 9.0;
int x;
System.out.println ("Sum of a and b is
if( a = b)
+ (a+b))
80
X = a;
switch (a+b) {
case 0: System.out.println (x);
default: System.out.println (x) ;

class Variables { public static void main(String[] args) { .
Follow these steps:
Open the Java file Errors.java.
Attempt to compile the program. You'll notice the compilation will fail due
to some errors. Fix all the compilation errors and compile the program
again. Every time you fix an error, add a comment to the line you fixed and
indicate which of the three types of errors it was.
Now run the program. Once again, you'll encounter some errors (this time,
runtime errors). Fix these errors and run the program once again to see if
it works.
Now run the program and notice the output. You'll notice that there are
some logical errors in the code. Fix these errors and run the program once
again to see if it now correctly displays what it should.
