The following code segment demonstrates short circuit evaluation: if (0 == 1 && 2 + 2...
Question 2 1 point possble (graded) Consider the following code segment. String a- a0 if (a-0") else if (a"1") else if (a" else( System.out.printin("a is 0 System.out.printin("a is 1! System.out.println("a is al") System.out.println(a is something else!) Which of the following statements about the code segment is true? It produced "a is 0!" as output It produced "a is 1!" as output It produced "a is a!" as output It produced "a is something else!" as output It results in an...

a. Rewrite the following code segment using if statements. Assume that grade has been declared as of type char. char grade= 'B';; switch (grade) { case 'A': System.out.println("Excellent"); break case 'B': System.out.println("Good"); default: System.out.println("you can do better”); } - b. write Java code that inputs an integer and prints each of its digit followed by ** e.gif the integer is 1234 then it should print 1**2**3**4 e.g. if the integer is 85 then it...
1. What is the output of the following code segment? int array[] = { 8, 6, 9, 7, 6, 4, 4, 5, 8, 10 }; System.out.println( "Index Value" ); for ( int i = 0; i < array.length; i++ ) System.out.printf( "%d %d\n", i, array[ i ] ); 2. What is the output of the following code segment? char sentence[] = {'H', 'o', 'w', ' ', 'a', 'r', 'e', ' ', 'y', 'o', 'u' }; String output = "The sentence...
31. The following code segment is syntactically correct: int number{20}; cout << number << setbase(16) << " " << number << setbase(10) << " " << number << showpos << " " << number << endl; T__ F__ 32. The following statement wants to determine if ‘count’ is outside the range of 0 through 100: if (count < 0 && count > 100) T__ F__ 33. There is...
QUESTION 1 Which statement results in the value false? The value of count is 0; limit is 10. (count != 0)&&(limit < 20) (count == 0)&&(limit < 20) (count != 0)||(limit < 20) (count == 0)&&(limit < 20) 10 points QUESTION 2 If this code fragment were executed in an otherwise correct and complete program, what would the output be? int a = 3, b = 2, c = 5 if (a > b) a = 4; if (...
1. Consider the following code segment. String str = "AP"; str += "CS " + 1 + 2; System.out.println(str); What is printed as a result of executing the code segment? A: CS AP12 B: AP CS3 C: CSAP 12 D: APCS 12 E: APCS 3 2. Consider the following code segment. String dessert = "pie"; dessert += "straw" + dessert + "berry"; What is the value of dessert after the code segment has been executed? A: strawpieberry B: piestrawpieberry C:...
Problem 8)(Java code) Give the output of the following program segment if: (a) x=1 and y=1, (b) x=2 and y=2. if (x > 1) if (y > 2) Sysytem.out.println(2*x-y); else Sysytem.out.println(2*x+y); else if (y > 2) Sysytem.out.println(x-y); else Sysytem.out.println(x+y);
Consider the interface Predicate defined as follows. interface Predicate { boolean eval(int j); } Recall that you can check if an integer “i” is even by using the expression “i%2 == 0”. Write a class IsEven that determines whether a number is even: class IsEven implements Predicate { public boolean eval(int j) { } } For example, the following code Predicate p = new IsEven(); if ( p.eval(2)) { System.out.println("2 is even"); } if (! p.eval(3)) { System.out.println("3 is not...
Consider the following incomplete code segment, which is intended to print the sum of the digits in num. For example, when num is 12345, the code segment should print 15, which represents the sum 1 + 2 + 3 + 4 + 5. int num = 12345; int sum = 0; /* missing loop header */ { sum += num % 10; num /= 10; } System.out.println(sum); Which of the following should replace /* missing loop header */ so that the...
JAVA 5) What is the output of the following code? int a = 70; boolean b = false; if(a >= 70) { System.out.print(1); if(b==true) { System.out.print(2); } } else { System.out.print(3); if(b==false) { System.out.print(4); } } System.out.print(5); 6) What is the output of the code above using these initial values? int a = 43; boolean b = false; 7) The following method is SYNTACTICALLY correct (meaning it will compile). True or false? public boolean method() { int value = 5;...
