Understanding Test on JAVA Test P5

• Question 1. How much of the above block will result if we enter revenue = 1?

  switch (receiver) {
  
  case 2:
  
  System.out.println ('Van, Toan');
  
  break;
  
  case 3:
  
  System.out.println ('Flowers, Cups');
  
  break;
  
  default:
  
  System.out.println ('Immediately');
  
  break;
  
  }

  • Van, Toan
  • Flowers, Ly
  • Immediately
  • There is no answer
• Question 2. How much will the above block result if we enter revenue = 2?

  switch (receiver) {
  
  case 2:
  
  System.out.println ('Van, Toan');
  
  break;
  
  case 3:
  
  System.out.println ('Flowers, Cups');
  
  break;
  
  default:
  
  System.out.println ('Immediately');
  
  break;
  
  }

  • Van, Toan

  • Flowers, Ly

  • 1. Immediately
  • There is no right answer
• Question 3. How much of the above block will result if we enter revenue = 3?

  switch (receiver) {
  
  case 2:
  
  System.out.println ('Van, Toan');
  
  break;
  
  case 3:
  
  System.out.println ('Flowers, Cups');
  
  break;
  
  default:
  
  System.out.println ('Immediately');
  
  break;
  
  }

  • Van, Toan
  • Flowers, Ly
  • Immediately
  • There is no right answer
• Question 4. If color = DEN, what is the above command to print the result?

  mausac enum {DEN, LAM, LUC, PAGE};
  
  mausac color;
  
  char * t;
  
  switch (color) {
  
  case 0:
  
  t = 'Mau page';
  
  break;
  
  case 1:
  
  t = 'Mau den';
  
  break;
  
  case 2:
  
  t = 'Mau lam';
  
  break;
  
  case 3:
  
  t = 'Mau luc';
  
  break;
  
  default:
  
  t = 'Not in the list';
  
  break;
  
  }

  System.out.println (t);

  • Quick page

  • black

  • Quickly
  • There are no colors in the list
• Question 5. If color = DEN, what is the above command to print the result?

  enum mausac {DEN = 3, LAM, LUC, PAGE};
  
  mausac color;
  
  char * t;
  
  switch (color) {
  
  case 0:
  
  t = 'Mau page';
  
  break;
  
  case 1:
  
  t = 'Mau den';
  
  break;
  
  case 2:
  
  t = 'Mau lam';
  
  break;
  
  case 3:
  
  t = 'Mau luc';
  
  break;
  
  default:
  
  t = 'Not in the list';
  
  break;
  
  }
  
  System.out.println (t);

  • black
  • Blue
  • Quick page
  • Quickly
• Question 6. When executing the above block, what is the result?

  int s = 0;
  
  for (int i = 0; i <10; i ++)
  
  s + = i;
  
  System.out.println (s);

  • 45
  • 0
  • 55
  • No results were correct
• Question 7. What does this block do?

  int [] mang = new int [10];
  
  int s = 0;
  
  int j = 0;
  
  for (int i: mang) {
  
  i = ++ j;
  
  s + = i;
  
  }
  
  System.out.println ('S =' + s);

  • Enter data for the raw array.
  • Calculate the total integer array.
  • Enter data and calculate the integer array.

  • All is wrong

• Question 8. When executing the command block in the figure, what will be the result?

  int [] mang = new int [10];
  
  int s = 0;
  
  int j = 0;
  
  for (int i: mang) {
  
  i = ++ j;
  
  s + = i;
  
  }
  
  System.out.println ('S =' + s);

  • 1. S = 40
  • 1. S = 50
  • S = 55

  • S = 45

• Question 9. When executing the above block, what is the result?

  int [] mang = new int [10];
  
  int s;
  
  int j = 0;
  
  for (int i: mang) {
  
  s = 0;
  
  i = ++ j;
  
  s + = i;
  
  }
  
  System.out.println ('S =' + s);

  • Wrong command
  • S = 10
  • 1. S = 45
  • 1. S = 55
• Question 10. When executing the block, what is the result?

  int i = 0;
  
  due to {
  
  i + = 1;
  
  } while (i == 0);
  
  System.out.println ('i =' + i);

  • i = 0
  • i = 1
  • i = 2
  • All is wrong
