Javax ImageIO IIOException显然没有原因。

    public static void main(String[]args) throws IOException
{
    File actualDir = new File(\"C:\\\\Users\\\\Rowe\\\\Desktop\\\\testExpect\");
    String actualFiles[] = actualDir.list();
    File expectedDir = new File(\"C:\\\\Users\\\\Rowe\\\\Desktop\\\\testExpect2\");
    String expectedFiles[] = expectedDir.list();
    int[][] stats = new int[actualFiles.length][6];                             // Holds all info
            //Columns, Rows, Total, redMatches, shouldaBeenRed, badRed
    for(int i = 0; i < actualFiles.length; i++)
    {
        BufferedImage actualImage = null;
        System.out.println(actualFiles[i]);   //THIS PRINTS PROPERLY
        System.out.println(System.getProperty(\"user.dir\"));  //FOR TESTING
        actualImage = ImageIO.read(new File(\"C:\\\\Users\\\\Rowe\\\\Desktop\\\\testExpect\\\\\"+actualFiles[i]));   //ERROR HERE

        BufferedImage expectedImage = null;
        expectedImage = ImageIO.read(new File(\"C:\\\\Users\\\\Rowe\\\\Desktop\\\\testExpect2\\\\\"+expectedFiles[i]));  //THIS IMAGE WORKS
