for(int i = 0; i < 6; i++) { for(int j = 1; j <= 5; j++) { System.out.print(i + j + " "); } System.out.println(); } What is printed by the third iteration of the outer loop?

int n; for(n = 8; n < 30; n += 5) { // } System.out.print(n); What is printed when the loop above has finished?

In which instance can a loop not require braces?
when only one statement is to be repeated
Identify the true statements regarding Java loops. Select ALL that apply. Question 1 options: For loops are more susceptible to endless loop coding errors than while loops. A do-while loop always runs at least once. While loops are best when the number of loop iterations can be predetermined. A while loop might not run at all. Loops can be nested in other loops to any depth as desired.

int b =0, sum =0; while (b < 6) { ++b; if(b % 2 == 0) continue; b++; sum = sum + b; } System.out.print(sum); When the above program is run, the output would be 13?
False
4. for(int n = 0; n <= 12; n++) { 5. System.out.print(n + " "); 6. } 7. System.out.println(n); What is the output of line 7?
Nothing. Compilation fails
A while loop is a __?__ loop.

The Java continue statement causes execution to skip to
the next iteration in the loop
