Not too crazy, but what if you had opposite syntaxes? I'm gonna leave the replies to give some examples, but here's a short one:
"hello" = world
print("hello")
// Output:
world
while i < 11:
i-=1
//this would add i+1 until its greater than 11

It legitimately tells you your error and how to fix it. This is pure laziness what the hell is up with the description for this post anyways? Making it sound urgent or making yourself look like a fool?thethermometer6 months ago
smh why don't you just read your errors? It legit says it needs a semicolon after System.out.println(). Every statement in Java needs to end with a semicolon, unlike great Python. By the way, your not using Swing so just create a Java project. Also, if you want to print literally cat - 1, put quote. Otherwise, if you want to do math, don't put quotes,[deleted]

how to add jar file in java?BrianWillem2 years ago
Jar files can be uploaded to your project the same as other files. I put my jar files into a "jars" folder that I create in my repl.
From that point, you can compile and run your code from the command line:
javac -classpath .:./jars/* -d . Main.java
java -classpath .:./jars/* Main
If you want to configure the "Run" action, you can define a .replit file in your project and add the following line.
run = "export CLASSPATH=\".:./jars/*\"; javac -d . Main.java; java Main"
Configure these commands how do i embed the program into a website?Every time I try to open the embeded program in my website, the program won't load, it worked the first time i tried but since that happened it wont l

I'm not a Java expert, so I can't tell you exactly why this is the case, but change
System.out.println("Enter the operation");
String operation = sc.nextLine();
to
System.out.println("Enter the operation");
sc.nextLine(); String operation = sc.nextLine();
It might be because the last sc.nextDouble() doesn't catch the final newline in that input (you type the number and then a newline, but sc.nextDouble() might not catch that), so it "bleeds over" into the next input and thus causes the result o answered

@sprintokflash Hi Gingrbred,
I think on line 2, you have entered your class name as UserInput.
To solve the error you have to change your second line code to this:-

public class Main
That's it.
Thanks!

So you want them to be able to share a link with you that of their repl, where you can't edit it?

image why is the system.in.readDorshReal1 year ago
There are some problems in this code:
You are using the hasNext() method, which is more favourable in a recursive nature if you want to continue receiving input, suitable for a while loop instead of an if statement
You are using the read() function in conjunction with System.in along with the wrong input class (Scanner). Use a buffered reader instead to access read() method, or just replace it with in.nextChar()
Why are you using a char to hold a string input? A name contains more than one charaSuperUser1111 year ago
What are you trying to do?
If you simply want to print out what they entered, use this code (it's in java):
`try(BufferedReader br = new BufferedReader(new InputStreamReader(System.in))){
final String name = br.readLine();
System.out.println("Your name is: "+name);
}`
With some formatting that should work. If that wasn't what you were looking for then could you explain it to me? Thanks answered

When you do getRoot() it is replicating it and then getting it, DynamicSquid is correct, doing setNode() will work but you need to specify how it returns the node it's a copy of the original, so set the Node using setNode(), then specify which root to get, for example, use path.getRoot, and set the path with `System.out.println("Root Path: "

Baconman3211 year ago
I know basically nothing about java. However, I looked up length quickly. There are two types of length keywords. ".length()" is used for string objects only, while ".length" is used for arrays. replaceAll() needs 2 parameters. The first one is the character you are searching for. On line 57, you may want to use "account" instead of account. The second parameter is what you want to replace the character that it finds with. For instance: String replace = "hello world"; replace.replaceAll("l","e")Anyone know how to force a player to wear a skin in mine craft in 1 world using Java/ Java Script.I am working on a project I have due by next Sunday.Most
