Error: Duplicate local variable outa
コード：
else if (choice==1){
int a;
int b;
int c;
System.out.println("what is a ?");
a=myscan.next ; //line 36
System.out.println("what is b ?");
b=myscan.next ; //line38
System.out.println("what is c ?");
c=myscan.next ; //line40
double outa =(b + Math.sqrt((b*b)-4*a*c))/(2*a);
double outa =(b - Math.sqrt((b*b)-4*a*c))/(2*a); //line42
}
//quadratic formula ^^^^
