"and" statements

[Boyotbh]

I have only recently begun to use java, so apologies if this is a really stupid question, but how do you go about using and statements.

for example if a user has to input a variable and it has to be between 40 and 60, what would be the code used to do this.

I have been searching around the internet for a while and I can't find the answer anywhere.

Read a turorial; it saves you so much time. The 'and' operator is '&&' and your
boolean expression should look something like this:

[code=java]
if (input >= 40 && input <= 60) ...
[/code]

kind regards,

ok thanks very much.

I had been reading various tutorials on the if statement but hadn't been able to find the answer.

If you haven't already, add Sun's Java tutorial to your list. It's easy to navigate. For example, I found && in a few seconds:

Ah brilliant, I hadn't found that. Definitely getting bookmarked. I tried && and it isn't working currently, what is wrong with this

    public void stuff(int input)
    
    {
        if (input >= -40 && <=75) {
           other=input; 
    }
      
        else {
            System.out.println("not valid.");

if (input >= -40 && input <=75)

Expressions in Java should be fully spelled out. Java does not use the informal abbreviations people use, for example x < y < z must be written x < y && y < z.
