![continue statement
• The continue statement skips the current iteration of a loop
• In while and do loops, continue causes the control to go directly to the test
condition and then continue the iteration process
• In case of for loop, the increment section of the loop is executed before the test
condition is evaluated.

{
public static void main(String[] args)
{
int [] num = {10, 20, 30, 40, 50};

continue;

System.out.println( "i: "+i );

Java iterative statements
The document discusses different types of iterative statements in Java including while, do-while, for, enhanced for loops, and the continue statement. It provides the syntax and examples of each statement type. The while loop executes statements until a condition is false. The do-while loop executes statements once, then checks the condition. The for loop allows initialization, condition checking, and increment/decrement in the header. The enhanced for loop iterates over arrays or collections. The continue statement skips the current iteration in a loop.
