can you explain java problem

[buklu]

for ( int i=1; i<=7; i++ ) {                   what is the function of  @  and ""
for ( int j=1; j<=5; j++ ) {
System.out.print( "@" );
}
System.out.println( "" );
}

[buklu]

one more problem,what is the function of %s

 

System.out.printf( "[%s]\n", s1 );

I haven't touched Java in almost 10 years but the @ sign if just some text in that instance, the "" just means that whatever is inside the quotes is a string and this last one is an assumption but I think the [%s] will be substituting in the second param (s1), sort of like a C# string.Format("My name is {0}", "Josh")
