Method to convert String[] to int[]

[Sandeep Swaminathan]

Very basic question:

I'm trying to get input from the user in an array (in a method) using 'for' loop construct

for(int count=0;count<5;count++)
{
    BufferedReader stdin = new BufferedReader(new InputStreamReader(System.in));
    sample[count] = Integer.parseInt(stdin.readLine(sampleStr[count]));
}

sample[count] & sampleStr[count] are instance variables that I declare in the beginning

int[] sample;
String[] sampleStr

1. My doubt is can we use BufferedReader to get input in an array or is there any other efficient way?
2. How to convert string[] to int[]?

I don't think there is a convenience method for this in the core API. You'll have to instantiate the int array, and parse each element of the string array to the int array.

Ok. So you meant to say something like this right?

public int[] convertStringArrtoIntArr(String[] strarray)
{
	
    int intarray[] = new int[strarray.length];
        for (int count = 0; count < strarray.length; count++) 
        {
	    intarray[count] = Integer.parseInt(strarray[count]);
	}
    return intarray;
}

That's the way I would have done it, although I might have named the method "toIntArray"; the StringArray part can be deducted from the parameter list.
