java if else statement
- by user554320
I am a new student who is trying to use java if else statements at the moment.
I have attched my class and i need to say if this code get 0 errors for all 4 errors(error11, error12, error13 and error14), need to display the text "Answer".
This code was working without the if else statements and there are 2 errors in those 2 lines.
Please explain me how to do it?
public static void deltaR()
{
int x;
int x11, x12, x13, x14;
int x21, x22, x23, x24; //inputs
double w10, w11, w12;//weights for first neuron
int d11, d12, d13, d14;//desired output for first neuron
double net11, net12, net13, net14;//sum of weights times inputs
int y11, y12, y13, y14;//outputs
int error11, error12, error13, error14;//error
//double w20, w21, w22;//weights for second neuron
//int d21, d22, d23, d24;//desired output for second neuron
//double net21, net22, net23, net24;//sum of weights times input
//int y21, y22, y23, y24;//outputs
//int error21, error22, error23, error24;//error
if (error11 = 0, error12 = 0, error13 = 0, error14 = 0)
{
System.out.println("Answer");
}
else if (error11 != 0, error12 != 0, error13 != 0, error14 != 0)
