输出: java i is smaller than 15A nested if is an if statement that is the target of another if or else. Nested if statements means an if statement inside an if statement. Yes, java allows us to nest if statements within if statements. i.e, we can place an if statement inside anothe...

You could also switch the string "123" and value variable in the statement, like this: public boolean isValid(String value) { return "123".equals(value); } This version actually has the advantage, that if value is null (does not point to a String object, but to nothing), this ver...

If no case value matches the switch expression value, execution continues at the default clause. This is the equivalent of the “else” for the switch statement. break The break statement is used inside the switch-case statement to terminate the execution of the statement sequence. The control ...
// specified condition inside if statement if (a>=5){ /* * if the condition is satisfied then * print the below statement */ System.out.println("a is 10"); } } } Output: Java If-else This is also known as if-then-else. Here, we specify the condition not only in the if-stat...
statement; } Thewhilekeyword executes the statements inside the block enclosed by the curly brackets. The statements are executed each time the expression is evaluated to true. Main.java void main() { int i = 0; int sum = 0; while (i < 10) { ...
Java's if-else is a two-way conditional branching statement. It can be used to route program execution through two different paths. The if statement can be used as an if-else-if ladder and can be nested one if statement inside another.
In Java, there are several ways to control the flow of the code: if and if-else statements switch statements while and do-while statements for and enhanced for statements break and continue statements The if Statement The if statement is probably the most common form of flow control, regardles...
The basic syntax of an if statement in C is as follows: if(condition){ // block of code to be executed if the condition is true } The condition inside the parentheses is evaluated. If the condition is true (non-zero), the block of code inside the curly braces is executed. If the ...
