import java.io.FileNotFoundException;
import java.io.IOException;
import org.apache.poi.xssf.usermodel.XSSFCell;
import org.apache.poi.xssf.usermodel.XSSFEvaluationWorkbook;
import org.apache.poi.xssf.usermodel.XSSFRow;
import org.apache.poi.xssf.usermodel.XSSFSheet;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
public class ExcelTest {    
    public static void main(String[] args) throws IOException {     
     String value = getExcelData("sheet1",2,2);
     System.out.println(" Cell Value " + value);     
    }   
    public static String getExcelData( String sheetName , int rowNum ,int cellNum) throws IOException{      
         FileInputStream fInput = new FileInputStream("C:\\Users\\xxxx\\Excel Data.xlsx");
         XSSFWorkbook wb = new XSSFWorkbook(fInput);
         XSSFSheet sheet = wb.getSheet(sheetName);
         XSSFRow row = sheet.getRow(rowNum);

For classes in the standard Java Runtime, the easiest, simplest answer is always going to be to install a JDK, and to compile and run your Java Applications using it. Your Installed JREs preference page should ideally only list JDKs.
