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.

You are almost there. the variable spass needs to be initialized as you are using if blocks without final else. Either you give spass="" or change final else if to else as below. 

    Scanner scan = new Scanner(System.in);
    System.out.println(" Input first password ");
    String pass1 = scan.nextLine();
    System.out.println(" input second password ");
    String pass2 = scan.nextLine();
    // problematic part here.
    String spass;
    if (pass1.length() > pass2.length()) {
        spass = pass2;
    } else if (pass1.length() < pass2.length()) {
        spass = pass1;
    } else {
        spass = null;
    }
    System.out.println("result: " + spass);

your problem is just a formating problem, if statements are formatet like this:

if(condition){
    do_something;
}else if( second_condition ){
    do_something_else;
}else{
    alternative;
}

In your case it seems that you dont know where to set semicolons ;

You have to set semicolons inside the if block like this:

String spass;
If (pass1l > pass2l){ 
    //Here semicolon
    spass = pass2;
} else if (pass1l < pass2l) {
    //Here semicolon
    spass = pass1;
}else if (pass1l == pass2l) {
    //Here semicolon
    spass = null;
}
//No semicolon at the end of the if-else-statement
