I think error in this line where i am sending the value through string Connection connection = DriverManager.getConnection ( "jdbc:microsoft:sqlserver://localhost:1433","sa",""); import java.sql.*; //import mssqlserver.*; public class TestSQLCON { public TestSQLCON() throws Exception { // Get connection DriverManager.registerDriver(new com.microsoft.jdbc.sqlserver.SQLServerDriver()); System.out.println(); System.out.println("Successfully connected one"); System.out.println(); Connection connection = DriverManager.getConnection ( "jdbc:microsoft:sqlserver://localhost:1433","sa",""); if (connection != null) { System.out.println(); System.out.println("Successfully connected"); System.out.println(); // Meta data DatabaseMetaData meta = connection.getMetaData(); System.out.println("\nDriver Information"); System.out.println("Driver Name: " + meta.getDriverName()); System.out.println("Driver Version: " + meta.getDriverVersion()); System.out.println("\nDatabase Information "); System.out.println("Database Name: " + meta.getDatabaseProductName()); System.out.println("Database Version: "+ meta.getDatabaseProductVersion()); } } public static void main (String args[]) throws Exception { TestSQLCON test = new TestSQLCON(); } } so please help me

HCL,
2 6474public class AboutStrings{ public static void main(String args[]){ String s1="hello"; String s2="hel"; String s3="lo"; String s4=s2+s3; //to know the hash codes of s1,s4. System.out.println(s1.hashCode()); System.out.println(s4.hashCode()); // these two s1 and s4 are having same hashcodes. if(s1==s4){ System.out.println("s1 and s4 are same."); }else System.out.println("s1 and s4 are not same."); } } Somebody told me that, == operator compares references of the objects. In the above example even though s1 and s4 are refering to same object(having same hash codes), it is printing s1 and s4 are not same. Can anybody explain in detail why it is behaving like this? Thanks in Advance RavuriVinod

Write a java program to find the route that connects between Red and Green Cells. General Rules for traversal 1. You can traverse from one cell to another vertically, horizontally or diagonally. 2. You cannot traverse through Black cells. 3. There should be only one Red and Green cell and at least one of each should be present. Otherwise the array is invalid. 4. You cannot revisit a cell that you have already traversed. 5. The maze need not be in the same as given in the above example
