Question

When you write an if-else statement, under what circumstances do the statements that appear after the else clause execute?

Short answer

The statements after the "else" clause in an if-else statement are executed when the condition in the "if" part of the decision-making construct is false. In other words, if the "if" condition is not met, the "else" block will execute.

Step-by-step solution

Understanding if-else statements

An if-else statement is a decision-making construct in computer programming languages. It consists of two parts: the "if" part, which contains a condition, and the "else" part, which contains the statements that will execute if the condition in the "if" part is false. The structure of an if-else statement looks like this: ``` if (condition) { // statements to be executed if the condition is true } else { // statements to be executed if the condition is false } ```

Identify the circumstances for executing statements after "else" clause

The statements after the "else" clause will execute when the condition in the "if" part of the if-else statement is false. If the condition is true, the statements inside the "if" block will execute, and the statements inside the "else" block will be skipped. In summary, the statements after the "else" clause execute when the "if" condition is not met. For example: ``` int a = 10; int b = 20; if (a > b) { // the condition is false (a is not greater than b) // this block will be skipped System.out.println("a is greater than b."); } else { // this block will be executed because the condition is false System.out.println("a is not greater than b."); } ``` In this example, the output will be "a is not greater than b.", because the condition "a > b" is false, and thus, the statements after the "else" clause are executed.
