can you kindly help me check what is wrong. thanks!

Do you seriously expect us to read such a big blob of unformatted code? Please add a [code] tag just before the start of your code and put a [/code] tag after the end of your code (edit your original replies and please don't throw that huge blob of code at us again).

kind regards,

Jos

I am sorry.
Is this what i am supposed to do?

thanks

[JosAH]

I am sorry.
Is this what i am supposed to do?

thanks

Yep, much better; but also realize that (almost?) nobody is going to read and analyze all that code; it'd be much better if you post an as short as possible example that compiles and also shows your problem. Help us to help you.

kind regards,

Jos

We can't check your project like this.
Make another sample code to execute your main problem.we will check that.

Hi,

i have already solved tat problem. thanks

I got some maths coding to ask..

For example,

f1=2
d1=5

f2=4
d2=7

f3=????
d3=10

This is the formula i need to input=>(f1xd1)+(f2xd2)+(f3xd3)=0 (Equate everything equal to zero)
=> (2x5)+(4x7)+(f3x10)=0
=> f3=? (I need to get this answer)

How do i write this codings?

hope to get a reply soon.
thanks!

[UJJAL DHAR]

I think its simple

double f3=(-1)((f1xd1)+(f2xd2))/d3;

in f3 you will get the result

[ivy]

how to import audio into my program?

the user will click on the jButton, then the audio start playing...

[UJJAL DHAR]

See books or google. There are lots of example of it.
If you are unexperienced in google searching

Search in google writing

Hi there,
I dunno what is wrong with my program. when i input F1=2, D1=5,the rest assume to be zero.
i will get 0.0 for my "Maxbending_pointload_and_cantilever1"
may i know what is wrong?

KeyListener listener1 = new KeyAdapter() {
		public void keyReleased(KeyEvent e) {
			
			 double F1 = 0.0;  //  @jve:decl-index=0:
			 double F2 = 0.0; 
			 double F3 = 0.0;
			 double D1 = 0.0;  //  @jve:decl-index=0:
			 double D2 = 0.0; 
			 double D3 = 0.0;
			
if (getJRadioButton9().isSelected() && getJRadioButton11().isSelected() != getJRadioButton7().isSelected()!= getJRadioButton6().isSelected()!= getJRadioButton12().isSelected()!= getJRadioButton13().isSelected()) {
			 
				if(!getF2().getText().equals("")){
				 F2 = (Double.parseDouble(getF2().getText()));
			     }
			     
				if(!getD2().getText().equals("")){
					 D2 = (Double.parseDouble(getD2().getText()));
				     }
			    
				if(!getF3().getText().equals("")){
					 F3 = (Double.parseDouble(getF3().getText()));
				     }
			    
				if(!getD3().getText().equals("")){
					 D3 = (Double.parseDouble(getD3().getText()));
				     }
			    
				if(!getF1().getText().equals("")){
					 F1 = (Double.parseDouble(getF1().getText()));
				     }
			    
				if(!getD1().getText().equals("")){
			    	 D1 = (Double.parseDouble(getD1().getText()));
			     }
			     
			    	 double result1 = Formula.P1_pointload_and_cantilever1(F1,F2,F3);
			    	 jLabel19.setText(""+result1);
			    	 double result2 = Formula.Maxbending_pointload_and_cantilever1(F1,F2,F3,D1,D2,D3);
			    	 jLabel22.setText(""+(result2));
			    	 jLabel37.setText(""+(Math.abs(result2)));
			 }

this is my formula

 public static double P1_pointload_and_cantilever1(double F1, double F2, double F3 ) {
        return(F3+F2+F1) ;    
    }  
    //this is the Max bending
    public static double Maxbending_pointload_and_cantilever1(double F1, double F2, double F3, double D2, double D1, double D3  ) {
   return((F1*D1)+(F2*D2)+(F3*D3)) ;
