The restrictions are:

  • You cannot remove entries from the collection while traversing it
  • You cannot modify the current entry in the collection while traversing it

Hence it is not usable in cases where you have to modify or delete entries from a collection while looping through it.

How do you exit in nested loop in java?

You may exit a nested loop in Java using a break with a label for the outer loop.


For each loop in Java 5?

The enhanced for loop, new to Java 6, is a specialized for loop that simplifies looping through an array or a collection. In this chapter we're going to focus on using the enhanced for to loop through arrays. We'll revisit the enhanced for as we discuss collections in the future chapter. Instead of having three components, the enhanced for has two. for(declaration : expression) The two pieces of the for statement are • declaration The newly declared block variable, of a type compatible with the elements of the array you are accessing. This variable will be available within the for block, and its value will be the same as the current array element. • expression This must evaluate to the array you want to loop through. This could be an array variable or a method call that returns an array. The array can be any type: primitives, objects, even arrays of arrays. Using the above definitions, let's look at some legal and illegal enhanced for declarations: String [] sNums = {"one", "two", "three"}; // legal 'for' declarations for(String s : sNums) ; // loop thru the array of Strings The enhanced for loop assumes that, barring an early exit from the loop, you'll always loop through every element of the array. The following discussions of break and continue apply to both the basic and enhanced for loops.


Which Loop avoids check at every iteration?

All loops available in Java (for, while, do-while) have a loop termination condition that would get executed during every iteration of the loop. Without checking the loop condition the loop cannot be terminated and hence avoiding the loop condition check during iteration is not logic and Java does not do it.


What are various loops available in java?

Java has three kinds of loops 1. For Loop 2. While Loop 3. Do - While Loop Both For loop and While loop would iterate through a certain lines of code within the loop's limit as long as the loop condition is satisfied. A do while loop would execute the loop once even before checking the condition. So in a do while loop, even if the loop condition is not satisfied the loop would execute once. Example Declarations: for(int i = 0; i < n; i++) { ..... } while (i < n) { ... i++; } do { ... i++; } while (i < n) ;


Why do you use the loops in java?

You use loops in Java when you want a set of actions to be repeated until a particular condition is met or for a certain number of times.The different types of loops in Java are:For LoopsDo-While LoopsWhile Loops

What is a nested loop in java?

A nested loop is a (inner) loop that appears in the loop body of another (outer) loop. The inner or outer loop can be any type: while, do while, or for. For example, the inner loop can be a while loop while an outer loop can be a for loop.
