With Robot Framework, we can use the built-in FOR loop construct in combination with Python code for loops with dictionaries. Here’s an example of how to do this: Define your dictionary in a test case or keyword: *** Test Cases *** Example Test Case ${my_dict}= Create Dictionary ke...
Since Java 1.5, the for-each loop or enhanced for loop is a concise way to iterate over the elements of an array and a Collection. Since Java 1.5, thefor-eachlooporenhancedforloopis a concise way to iterate over the elements of an array and a Collection. Simply put, thefor-eachloop ...

In this code, you use theprintln()method to print the second element of thepasswordarray. (For more on theSystem.out.printlnstatement, check out our tutorialHow To Write Your First Program in Java.) The second element has an index of1because array elements are numbered starting at 0, as ...
Java – Iterate over String Array To iterate over elements of String Array, use any of the Java Loops like while, for or advanced for loop. The index of string array starts from 0 to array length – 1. We can use this information and write a loop to iterate over string array elements...
Finally, we use the “RAISE NOTICE” statement to print the bike_number and bike_price: That’s all about using a “CONTINUE” statement in PostgreSQL. Conclusion In PostgreSQL, loops are used in the queries to perform single code/statements for multiple rows in the table. The continue state...
To retrieve a value from a HashMap, we use the get method. It takes a key as a parameter. Main.java import java.util.HashMap; import java.util.Map; void main() { Map<String, String> capitals = new HashMap<>(); capitals.put("svk", "Bratislava"); capitals.put("ger", "Berlin"...
Note that "!" means "not" in Java. So the controlling statment is "while not done". The "while loop" can be used forallof your looping needs. However, it is a standard that if you know in advance how many times you need to go through your loop, you use a "for loop". It is...
Launched in 1995, Java is among some of the oldest programming languages, yet it is most versatile when it comes to software and app development. Let’s talk about some of its use cases. However, there are different java ebooks for beginners through which they can learn about java programmin...
Example 5 - Nested for loops However, if you just want to operate on the value of the sequence without considering its corresponding position in the sequence, you can use the for loop given below. python rows=5foriinrange(1, rows +1):forjinrange(1, i +1):print(j, end=" ")print...
