In a grade table, total and count are int variables holding one row’s sum and its number of scores. Which expression gives the exact decimal average, such as 86.33 rather than 86?

This code is meant to add up every element of pts. What does it actually print?int[][] pts = { {3, 4}, {5, 6}, {1, 2} }; int total = 0; for (int row = 0; row < pts.length; row++) { total = 0; for (int col = 0; col < pts[row].length; col++) { total += pts[row][col]; } } System.out.println(total);

A nested loop with the row loop on the outside prints a 2-row by 3-column grid in row-major order. To print it in column-major order (column by column) instead, what should change?

This loop is meant to remove every value less than 10. What does the code print?ArrayList nums = new ArrayList(); nums.add(4); nums.add(6); nums.add(15); nums.add(3); for (int i = 0; i < nums.size(); i++) { if (nums.get(i) < 10) { nums.remove(i); } } System.out.println(nums.get(0) + " " + nums.size());

Assume ArrayList has been imported. Which line of this code causes a compile error?ArrayList tags = new ArrayList(); tags.add(“clearance”); int n = tags.length; System.out.println(“Count: ” + n);

This code is meant to find the largest value in lows. What does it print?int[] lows = {-8, -3, -5}; int warmest = 0; for (int t : lows) { if (t > warmest) { warmest = t; } } System.out.println(warmest);

What does this code print?int[] a = {4, 9, 2, 6}; a[1] = a[0] + a[3]; a[0] = 7; System.out.println(a[1]);

What is printed by the following code?int battery = 15; if (battery > 50) { System.out.print(“full “); } else if (battery > 20) { System.out.print(“low “); } System.out.print(“checked”);

This code prints a 4 by 4 square of # symbols. Which replacement for the inner loop header makes it print a right triangle instead, with one # on the first line, two on the second, three on the third, and four on the fourth?for (int row = 1; row

What is printed by the following code?ArrayList temps = new ArrayList(); temps.add(72); temps.add(85); temps.add(91); temps.add(68); int checked = 0; for (int i = 0; i < temps.size(); i++) { checked++; if (temps.get(i) > 80) { break; } } System.out.println(checked);
