Current If statement involving String

//Essentially my assignment is supposed to take 2 words, calculate the smallest of the two which I have done, but now I need to reference the smallest word itself instead of the number. Which I believe requires an If statement, but I cannot get my String to initialize and the console gets picky when I end the program with the system.out.println command. 

Scanner scan = new Scanner(system.In); 
System.out.println(" Input first password ");
String pass1 = scan.nextLine();
Int pass1l = pass1.length();
System.out.println(" input second password "); 
String pass2 = scan.nextLine();
Int pass2l = pass2.length();
Int spassl = Math.min(pass1l,pass2l);
// problematic part here. 
String spass;
If (pass1l > pass2l){ spass = pass2}
else if (pass1l < pass2l) {spass = pass1}
else if (pass1l == pass2l) {spass = null;};
// Also the Else if statements come up as not statements        and the first is an illegal start of an expression.

// Then if I fix those I call spass with system.out and it says it's not initialized. I just started learning basic Java, I've used processing before but not for String related if statements, only integers.
