Explanation of Solution
Given statements:
1 + "Welcome " + 1 + 1
Explanation:
The above statement will print “1Welcome 11”. In java “+” is used to merge the java strings using “+” operator. So while executing the statement, the number “1” is concatenate with string “Welcome” followed by “1+1”.
Given statements:
1 + "Welcome " + (1 + 1)
Explanation:
It force “(1+1)” to be executed first, as it is enclosed within the parenthesis so the value returned is “2”. So while executing the statement, the number “1” is concatenate with string “Welcome” followed by value “2”. So the result will be “1Welcome 2”
Given statements:
1 + "Welcome " + ('\u0001' + 1)
Explanation:
It force “('\u0001+1')” to be executed first, as it is enclosed within the parenthesis so the value returned is “2”. So while executing the statement, the number “1” is concatenate with string “Welcome” followed by value “2”. So the result will be “1Welcome 2”
Given statements:
1 + "Welcome " + 'a' + 1
Explanation:
The above statement will print “1Welcome a1”...

The program should display the corresponding day of the week, where 1 = Monday, 2 = Tuesday, 3 = Wednesday, 4 = Thursday, 5 = Friday, 6 = Saturday, 7 = Sunday. The program should display an error message if the user enters a number that is outside the range of 1 through 7.arrow_forward
