If we invoke the static method showTest(), what will the output be?

• none, the class will not compile

• True

• False

What will the variable code equal after the method convertCode() is run?

• The code will not compile

• 100237

• 237

An object is an instantiation of a class. Pernyataan ini dapat diterjemahkan sebagai -sebuah obyek adalah sebuah perwujudan dari sebuah kelas.

• True

• False

What will be the output?

• The code will compile but have runtime error

• The code will not compile because the Student class located in package model could not be accessed from any class outside its package

• The code will not compile because the Main class should not have public modifier

• The code will compile and run fine

What will be the output of this class will be when compile and run?

• Output is 2

• The file will not compile because we can’t directly access method increment inside the static method (the object should be instantiated first then use the object to access increment method)

• The file will compile, but will give an error when run

• Output is 1

What code should be put to print the length of the second element of the first dimension of the array named arr, which is { 4, 5 }?

• System.out.println(test.arr[0].length);

•  System.out.println(test.arr.length);

• System.out.println(test.arr[1].length);

• System.out.println(test.arr[1].length());

•  It will compile and output 21 to the screen

• It will compile, but will produce interpreter error when executed

• It will not compile and give the compile error

• It will compile and output 20 to the screen

What will be the output of this class will be when compile and run?

• Output is 1

• Output is 2

• The file will not compile because we can’t directly access method increment inside the static method (the object should be instantiated first then use the object to access increment method)

• The file will compile, but will give an error when run

What code should be put to print the value of 5 from the array named arr?

• System.out.println(test.arr[1][0])

•  System.out.println(test.arr[1][1]);

• System.out.println(test.arr[0][1]);

Select one:

• True

• False
