Objectives Continue to understand programming constructs in Java: -the while loop -the do-while loop -the for loop Look at the break statement Look at the continue statement Let’s get started!

Nesting for Loops To get the above output, we can use:

Nesting for Loops A program that will list all the letters contained in a string and will also count the number of different letters.

The break Statement Syntax: break; Breaks out of a loop or switch statement If used in an if statement, then the if statement HAS to be in a loop or a switch, and the program will break out of that container loop or switch statement. Can we write the above with a for loop?

The break Statement We can also create a labeled break, to break out of nested loops. label_name: loop1 loop 2 loop3 break label_name; end loop3 end loop2 end loop1 Will break out of all the loops and proceed with the next statement below the 3 labeled loops. See example of ListLetters.java

The continue Statement Syntax: continue; Continues with the next iteration of the loop. See program ContinueDemo.java The continue statement can also refer to a label, if we want to continue the next iteration of an outer loop.

Fun In Class Example Write a program called MultiplicationTable.java that prints the multiplication table for a particular integer, input by the user, times 1 till times 12 of that integer.
