Urgent Help Needed for some minor Bluej Error

[IITian]

I tried this code , it works fine :-

import java.util.*;
public class god {
    public void main() {
        float chalnabey;
        Scanner in=new Scanner(System.in);
        
        System.out.println("t");
    }
}

But when i add a line for taking input , the red bar at left goes on progressing and it never runs ! Why ???

import java.util.*;
public class god {
    public void main() {
        float chalnabey;
        Scanner in=new Scanner(System.in);
        chalnabey=in.nextFloat();                                             //This is addition to last code
        System.out.println("t");
    }
}

Please help fast , tommorows my exams :(

Could you explain what this means?

...and it never runs ! Why ???

How are you sure that it never runs? Have you tried entering a number to see what happens?

It might be clearer to you that you need to enter a number if you add a prompt, a String that reminds you to enter data:

import java.util.*;
public class god {
    public void main() {
        float chalnabey;
        Scanner in=new Scanner(System.in);
        System.out.print("Please enter a number: ");
        chalnabey=in.nextFloat();                         
        System.out.println("t");
    }
}

Also, we greatly appreciate it if you leave "urgent" and similar messages out of your question. Your question is no more important than any other question on this site. You'll be much better served if in your question heading you post a very brief summary of your current problem rather than non-specific text such as "urgent help needed for some ...". Tell us exactly what is wrong in that heading, but again, without the urgency.

I compiled , it compiles without any error but when i right click and select "new void main()" then JVM loader at left seems to load indefinatly , i didnt find any possible error in code but when i remove that line "chalnabey=in.nextInt();" , it works perfectly ?

Okay next time o=i will not use 'urgent' and similair words :)

okay if you are using BlueJ
then here is the error.your program works fine...but the red bar at left goes on progressing tells you that your program is running.
So what you have to do is open the terminal window by pressing Ctrl+t and the program shall run fine
