that line calls the min(a,b) method
these lines call the min(a,b,c,d) method

Thank you I have passed the challenge the error was calling min(min(a,b),min(c,d));in the main method. But still can't understand why my main method did not call the min (a, b) and (a, b, c, d) and still got verified. If you know kindly explain.

Do you mind explaining to me how you understand the question to this challenge, may that way I can get the problem to my code. I have corrected it as you've said, but still won't work. I keep getting the "cannot find symbol"

In this code:
public static int min(int a, int b, int c, int d) {
int m3 = min(a,b);
int minValue;
int m1;
if(c<d){
c=m1;
}
else {
d=m1;
}
if(m1<m2){
m1=minValue;
}
else{
m2=minValue;
}
return minValue;
}
you need to swap the variables around because of the same reason pointed out below. Also there is no variable m2 declared in this, however the code is using one. I think you meant m3.

In this method:
The assignment operator (equals sign '=') assigns the variable on the left to the value on the right. This code should have m2 = (a or b), not the way that it is coded.

Next time just use the slide and don't copy and paste your code:
.
![]()
