Code Java:

---

public class Bhaskara {
int a;
int b;
int c;
int d;
double x;
double x2;
public Bhaskara () {
a=1;
b=1;
c=1;
d=1;
}
 
 
public void seta ( int a );
{ 
valor_a=a;
 
}
 
public void setx ( double x );
{
valor_x=x;
}
 
public void setx2 ( double x2 );
{
valor_x2=x2;
}
 
 
public void setb ( int b );
{
valor_b=b;
 
}
 
public void setc ( int c );
{
valor_c=c;
 
}
 
int d = b*b- (4*a*c);
 
void apply () {
if (d = 0)
       public double xvalue;
       x = -b + Math.pow (d;1/2)/2*a;
       return x;
 
 
 
else (d < 0) 
public staticm void main ( string args [] ) {
    System.out.println ("There'so possible answer");
}
 
else ( d > 0 )
public double xvalue;
x = -b + Math.pow (d;1/2)/2*a;
return x;
public double x2value;
x2 = -b - Math.pow (d;1/2)/2*a;
return x2;
}

Those images are too small to see the errors.

What seems to be the problem exactly? Please give us as much detail as possible.

Looking at the code, I can see lot's of errors straight away. I suggest going back to basics - The Java™ Tutorials

My first hint would be to look at the methods.

Code Java:

---

void apply () {
if (d = 0)
       public double xvalue;
       x = -b + Math.pow (d;1/2)/2*a;
       return x;

The error says : " illegal start of expression " in public double x value

Like I said, there are lots of errors in your code.

• Your methods are wrong. Delete ;
• d is a duplicate variable.
• valor_a, valor_b etc are undefined.

Plus x = -b + Math.pow (d;1/2)/2*a; is completely wrong.

Im using BlueJ.... i think its kinda different

Different from what? The syntax is the same, right?
