You need to use equals() to test strings for equality in java.

@ThePhantomUpvoter can you help me in creating the code using equals()

You are kidding right? You are seriously unable to to write if(name.equals("anoop")?

Solution 1

In Java, '=' is not a comparison operator but assignment. For comparison, you need to replace it with '=='.

Solution 4

For assiging we use single = sign, but for comparing we use double = sign.

C#

String name=adminname.getText();
        String password=adminpassword.getText();
        if(name=="anoop" && password=="sharma")
        {
            JOptionPane.showMessageDialog(rootPane, "Login successfull");
        }

This question is more that two years old and has already been answered. Also your "solution" is incorrect, which you could have discovered by reading the others.

Solution 3

if(new String("test").equals("test")) 
{
  // Expression is true
}

if(new String("test") == "test")
{
  // Expresson is false since you are not comparing 
  // the same instance of the object to itself
}
