Use two if statements if both if statement conditions could be true at the same time. In this example, both conditions can be true. You can pass and do great at the same time. Use an if/else statement if the two conditions are mutually exclusive meaning if one condition is true the other condition must be false.

When you code an if statement within another if statement The statements are?When there is an if statement inside another if statement then it is called the nested if statement.

The first IF statement will handle the first outcome, while the second one will return the second and the third possible outcomes. Note: If you have Office 365 installed, then you can also use the new IFS function.
How do you optimize multiple if else statements in Java?

What are the looping statements in Java?
In Java, there are three kinds of loops which are – the for loop, the while loop, and the do-while loop. All these three loop constructs of Java executes a set of repeated statements as long as a specified condition remains true. This particular condition is generally known as loop control.
Are lots of if statements Bad?
The if statement is rarely considered as “evil” as goto or mutable global variables — and even the latter are actually not universally and absolutely evil. I would suggest taking the claim as a bit hyperbolic. It also largely depends on your programming language and environment.
Are nested if statements bad practice?
