#What is the symbol for does not equal in java code

It is simply the opposite of what the condition says. The not operator is probably the easiest to understand. Do not fall for this trap and make sure you always use the OR operator in the proper way.

#What is the symbol for does not equal in java code

Remember Java always executes code inside parenthesis first! In this case it looks inside the parenthesis, sees 3 or 5, and has no idea what that means. Even though it looks like it should work, it doesn't. Do not try to shorten your logic statements in this way, because Java doesn't understand what it means. Those just starting out believe that through clever use of parenthesis, they can make that mean that num1 can be equal to 3 or 5. The editor I use, Eclipse, will show this line as an error. There is a common mistake I ALWAYS see when people use the OR operator:

OR is when you need only one thing to be true I think the easiest way to put it is like this:ДЄND is when you need everything to be true Learning about the logical operators means that you too will need to brush up on your logic. The only time that if statement will be false is when num1 is not equal to 3 AND num2 is not equal to 5. Only one of them has to be true for that to happen. The OR operator allows just this, the ability to have an if statement be true if only one out of several conditions is met.Дo you see how this example of code is different from the previous? The code will run if num1 is equal to 3 OR num2 is equal to 5. Up until this point, it was ridiculously difficult to make a bunch of if statements so that the program will execute a piece of code if only one out of several conditions is true.

If num1 is equal to 3 and num2 is equal to 5, then output 'You win!'. Seems simple enough.Д«ut there has to be a better way than putting an if statement inside of another if statement!Дo you see how much cleaner that code looks? It even sounds better when you say it in English. If that one is also true, then it will print out 'You Win!' on the screen.

Then, if it's true, it will go on to the second if statement. Let's say you wanted your program to output 'You Win!' when num1 is equal to 3 and num2 is equal to 5.ДЇirst, Java will look at the first if statement. The best way to show how effective these are is to just show you how they make your code look a lot cleaner. It's really optional compared to the ones I will introduce, and these will be a whole heck of a lot useful to you now.Д¬onditional operators, like their relational counterparts, are also mostly used in if statements, while loops, and for loops. There are four logical operators in Java, however one of them is less commonly used and I will not discuss here. You can check out how they are used in the conditionals tutorial found in the Java for Beginners section of the site. Otherwise, the condition is true.Д«ecause you have seen the rest of the relational operators, I will not go over them here.

Now the if statement is true when the variable num is not equal to 3. Here is how it looks like in an if statement: The only addition I made from the previous list is the 'is not equal to' symbol. There should not be any other cases of their usage. Relational operators are used primarily in if statements, while loops, and on occasion for loops. I am going to complete the list, so you will have all of Java's relational operators in front of you.Д¬onditional symbols and their meanings Symbol You should have seen these operators before if you've been following these tutorials.
