Ok so I have to make a java program to search through an array using a binary search to find 45.3 but I am getting numerous class, interface, or enum expected errors starting after public static void main(String[] args) on line 23 can you guys help. thanks.
public class BinSearch
{
public static final int NOT_FOUND = -1;
public static int binarySearch(double[] arr, double x)
{
int low = 0;
int high = arr.length - 1;
int mid;
while (low <= high)
{
mid = (low + high) / 2;
if (arr[mid] > x)
{
high = mid - 1;
}
else if (arr[mid] < x)
{
low = mid + 1;
}
else
{
return mid+1;
}
}
return NOT_FOUND;
}
public static void main(String[] args)
{
int j,x;
double y,temp;
double[] arg= {-3.0, 10.0, 5.0, 24.0, 45.3, 10.5};
int i=0;
for (j = 1; j<arg.length;j++)
{
if(arg[i]>arg[j])
{
temp = arg[i];
arg[i] = arg[j];
arg[j] = temp;
}
i++;
System.out.print(arg[j-1]+",");
}
x = binarySearch(arg, 45.3);
System.out.print("45.3 found at ");
System.out.print(x);
}
}
It looks like you tried to use public class BinSearch
as your main class. However, your parentheses enclose code before your main args.
public class MyClass {
//}// no bracket here
public static void main(String[] args) {
}
}
If you want to use a class to create Objects that use methods such as your public static final int
, create a new class before.
class NewClass {
}
public class MyClass {
public static void main(String[] args) {
}
}
