Basic Java program: coding error

[tamkas]

Hey guys,

I am very new in Java Program. I was trying to sort numbers in the program.

import java.io.*;
/*
* Main.java

public class SortNumbers{
public static void sort(double[] nums){
for (int i=0; i<nums.length; i++){
int min =i; // holds the index of the smallest element
for(int j=i; j<nums.length; j++)
{ if (num[j]<num[min])min = j;
}
// Now swap the smallest one with element i.
//This leaves all elements between 0 and i sorted.
double tmp;
tmp =nums;
nums=nums[min];
nums[min]=tmp;
}
}



public class Main {
/** Creates a new instance of Main */
public static void Main(String[] args) {
double[] nums = new double[10];
for(int i=0; i<nums.length; i++)
nums = Math.random() * 100;
sort(nums);
for (int i = 0; i<nums.length; i++)
System.out.println(nums);
}
}
}



I have got a following error:

class, interface or enum expected.

Thanks in advance.

Hi

Sorry to say, but your code looks bad. First of all, use an editor with syntax highlighting feature. That way you would avoid the first error : the comment was not closed, so extended over the first class. Second, indent your code consistently and post it between [tt][ignore]

[/ignore][/tt] and [tt][ignore]

[/ignore][/tt] tags to help us to read it.
