If these conditions were met we display, “Its the weekend in the month of June”. If you want to execute multiple statements for the else condition, enclose the code in curly brackets. We will see how to write such type of conditions in the java program using control statements. The else part of the if/else statement follows the same rules as the if part. Example. 632. Ultimately, it comes down to which you find easier to read and debug, but deep nesting can become unwieldy if you end up with a massive … Introduction Conditional statements and loops are a very important tool in programming. ... How can I create an if statement with 3 conditions? Related. In Java, what is the best way to determine the size of an object? If you only need to execute a single statement for the else condition, you do not need to use curly brackets. Live Demo. Next we added a “else if” statement to check for another condition. Java Conditional or Relational Operators: The relational operators determine the relationship that one operand has to the other. Java will test for that value and no other values. This means that once the end result of the expression is known, evaluation stops. For example, if a and b were both true, meaning the overall expression must evaluate to true, then c, d and e are not evaluated. ... { // Executes when the none of the above condition is true. } If the condition is TRUE, then he can apply for the job.

Java uses short-circuiting for those boolean operators, so both variations are functionally identical. Since the value of the number is 10, the test expression evaluates to true.Hence code inside the body of if is executed.. Now, … There aren't many things we could do with code that can only execute line-by-line unconditionally. That's what "flow control" means - guiding the execution of our program, instead of letting it execute line-by-line regardless of any internal … Output: i is smaller than 15; nested-if: A nested if is an if statement that is the target of another if or else. Note that Java conditional operators short-circuit. i.e, we can place an if statement inside another if statement. Within the Else statement, there is another if condition (called as Nested If).
