What are the different types of iterative statements?
Iterative Statements in PL/SQL
General Syntax to write a Simple Loop is: LOOP statements; EXIT; {or EXIT WHEN condition;}END LOOP;These are the important steps to be followed while using Simple Loop. 1) Initialise a variable before the loop body. 2) While LoopA WHILE LOOP is used when a set of statements has to be executed as long as a condition is true. The condition is evaluated at the beginning of each iteration. The iteration continues until the condition becomes false. The General Syntax to write a WHILE LOOP is: WHILEImportant steps to follow when executing a while loop: 1) Initialise a variable before the loop body. 3) FOR LoopA FOR LOOP is used to execute a set of statements for a predetermined number of times. Iteration occurs between the start and end integer values given. The counter is always incremented by 1. The loop exits when the counter reachs the value of the end integer. The General Syntax to write a FOR LOOP is:
Important steps to follow when executing a while loop: 1) The counter variable is implicitly declared in the declaration section, so it's not necessary to declare it explicity. NOTE: The above Loops are explained with a example when dealing with Explicit Cursors. The java programming language provides a set of iterative statements that are used to execute a statement or a block of statements repeatedly as long as the given condition is true. The iterative statements are also known as looping statements or repetitive statements. Java provides the following iterative statements.
while statement in javaThe while statement is used to execute a single statement or block of statements repeatedly as long as the given condition is TRUE. The while statement is also known as Entry control looping statement. The syntax and execution flow of while statement is as follows. Let's look at the following example java code. Java Program ipublic class WhileTest { public static void main(String[] args) { int num = 1; while(num <= 10) { System.out.println(num); num++; } System.out.println("Statement after while!"); } }When we run this code, it produce the following output. do-while statement in javaThe do-while statement is used to execute a single statement or block of statements repeatedly as long as given the condition is TRUE. The do-while statement is also known as the Exit control looping statement. The do-while statement has the following syntax. Let's look at the following example java code. Java Program public class DoWhileTest { public static void main(String[] args) { int num = 1; do { System.out.println(num); num++; }while(num <= 10); System.out.println("Statement after do-while!"); } }When we run this code, it produce the following output. for statement in javaThe for statement is used to execute a single statement or a block of statements repeatedly as long as the given condition is TRUE. The for statement has the following syntax and execution flow diagram. In for-statement, the execution begins with the initialization statement. After the initialization statement, it executes Condition. If the condition is evaluated to true, then the block of statements executed otherwise it terminates the for-statement. After the block of statements execution, the modification statement gets executed, followed by condition again. Let's look at the following example java code. Java Program When we run this code, it produce the following output. for-each statement in javaThe Java for-each statement was introduced since Java 5.0 version. It provides an approach to traverse through an array or collection in Java. The for-each statement also known as enhanced for statement. The for-each statement executes the block of statements for each element of the given array or collection. 🔔 In for-each statement, we can not skip any element of given array or collection. The for-each statement has the following syntax and execution flow diagram. Let's look at the following example java code. Java Program public class ForEachTest { public static void main(String[] args) { int[] arrayList = {10, 20, 30, 40, 50}; for(int i : arrayList) { System.out.println("i = " + i); } System.out.println("Statement after for-each!"); } }When we run this code, it produce the following output. What are the different types of iterative statements in Java?Java programming language provides following types of loop to handle looping requirements. Repeats a statement or group of statements until a given condition is true.. ' while' loop.. ' do while' loop.. ' for' loop.. What are the different types of iterative statement in C?Iteration statements are most commonly know as loops. Also the repetition process in C is done by using loop control instruction.. For Loop.. While Loop.. Do-while loop.. What are the two types of iterative statements?7.6 Iteration Statements. 1 The while Statement. The while statement evaluates a control expression before each execution of the loop body. ... . 2 The do Statement. The do statement evaluates the control expression after each execution of the loop body. ... . 3 The for Statement.. What are the types of iterative statements explain with example?These statements are commonly called as loops. A loop repeatedly executes the same set of instructions until a termination condition is met. Explanation: For example, if we want to print Hello for 10 times, we need to call the print statement 10 times.
