Thread: i'm getting th error, when i put a method to get the position of the smallest no

 public class   SmallestIndex {
 
 
	//This method returns the index of the smallest value in the array of given size
     private static int arrSize = 0;
 
 
	public static void  smallestIndex (int[] array) {
 
 
		int currentValue = array[0];
 
		int smallestIndex = 0;
 
		for (int j=1; j < arrSize; j++) {
			if (array[j] < array[smallestIndex])
				smallestIndex = j;
		}
		System.out.println();
		System.out.println("The smallest index is: "+ smallestIndex);
 
	}
	}

it compiles correctly but when run program this error come
--------------------Configuration: my - JDK version 1.6.0_27 <Default> - <Default>--------------------
java.lang.NoSuchMethodError: main
Exception in thread "main"
Process completed.

so to correct this when i put the static void main(String[]args) so many other errors come again!!!


pls help me correcting this... your members help is greatly appreciated..

thank you!!

so many other errors come again!!!

You need to post the full text of the errors you get so we can help you solve the problem.

so to correct this when i put the static void main(String[]args) so many other errors come again!!!

 
    public class SmallestIndex {
       public static void main(String[]args){
    static final int LINESIZE = 10;
    static final int MAXSIZE = 50;
    static final int MINVALUE = Integer.MIN_VALUE;
    private static int arrSize = 0;
 
    //This method returns the index of the smallest value in the array of given size
    public static void smallestIndex (int[] array) {
    int currentValue = array[0];
    int smallestIndex = 0;
    for (int j=1; j < arrSize; j++) {
    if (array[j] < currentValue)
    currentValue = array[j];
    }
    System.out.println();
    System.out.println("The smallest index is: "+ currentValue);
    }
 
    public static void printArray(int[] array) {
    System.out.println("The numbers in the array are: ");
    for (int j=0; j< arrSize; j++) {
    if (j%LINESIZE == 0 )
    System.out.println();
    System.out.printf("%5d", array[j]);
    }
    }
 
 
   }
}

i get the errors 16

illegal start of expression - 8 errors
';' expected - 5 errors
'.class' expected - 2 errors

Quick question: Why is it that you have arrSize = 0 and you make j < arrSize? Wouldn't the for loop only run once then, if at all?

*edit* I guess it's to initialize the variable but won't it just stay 0?

OH MY GOD!!!!!!

just correct me this,,, include or exclude....

I WANT TO GET THE INDEX OF LARGEST ELEMENT IN AN ARRAY

----------------------------------------------------------------------------------------------------------[

 
 
class small {
  // method to display the contents of an array
  static void displayData(int[] data)   {
    for (int index=0; index != data.length; index++)
      System.out.println(data[index]+"\t");
  }
 
  static int positionOfLargest(int[] data, int limit)   {
    // method to return the position of the largest item
    // in the data with bounds 0..limit
 
    int largest = data[0];
    int indexOfLargest = 0;
 
    for (int index=1; index <= limit; index++)  {
      if (data[index]> largest)  {
        largest = data[index];
        indexOfLargest = index;
      }
    }
    return indexOfLargest;
  }
 
 
 
  public static void main(String[] args)   {
    int[] data = {18,7,15,8,13};
 
    System.out.println("numbers\n");
    displayData(data);
 
    System.out.println("Index of Largest\");
   indexOfLarget(data);
 
  }
}

Does it work now? If not please show the problem and explain.

You cannot have "inner methods" in java. It looks like you have a method inside the main method.
