        if (number > 0) {
            System.out.println("The number is positive.");
        }
        else if(number < 0) {
            System.out.println("The number is not positive.");
        }
        else if (number > 0) {
            System.out.println("The number is positive.");
        }
        .
        .
        else {
             System.out.println("Congrats you just solved the math in here!");
        }

在第 14 行和第 15 行删除 (.) 试试这个。

if(true){
        
}
else if(true){
        
}
else if(true){
        
}
else{
        
}
