Is there a maximum number of "else" in a if else statement [closed]

I want to make a calculator for area and volume, but I've encountered a Problem. In the 143rd line of my code (marked with "-->" in the code) the "else" is marked as an Error and i cant run the code

...
        if (str.equals("Square") || str.equals("square"))
        {
        do
        {
...         
    else if(str.equals("Square volume") || str.equals("square volume")) {
...
    else if(str.equals("triangle") || str.equals ("Triangle")) 
        {
...
    else if(str.equals("circle") || str.equals("Circle"))
        {
...
    else if(str.equals("ball volume") || str.equals("Ball vloume"));
        {
...
---->   else if(str.equals("triangle volume") || str.equals("Triangle volume"));
            { //unexpected Problem
...
    }
        
    }
}
