int和布尔错误

Question

我有一个生成和错误的方法,预期int,但发现布尔值,但当我切换到布尔值时,它说相同的错误,但反向int和布尔值.这是我的代码:

private void compileDeclaration(boolean isGlobal) {
         if (equals(theToken, "int")) {
            accept("int");
            String ident = theToken;
            if (!isIdent(theToken)) t.error("expected identifier, got " + theToken);
            else if (isGlobal){
                symTable.allocVar(ident, isGlobal);
            }

            if (!isGlobal) cs.emit(Machine.ALLOC, symTable.stackFrameSize());
            //dprint("declaring int " + ident);
            theToken = t.token();
            accept (";");
        } else if (equals (theToken, "final")) {
            accept("final");
            accept("int");
            String ident = theToken;
            if (!isIdent(theToken)) t.error("expected identifier, got " + theToken);
            theToken = t.token();
            accept("=");
            int numvalue = new Integer(theToken).intValue();
            if (!isNumber(theToken)) t.error("expected number, got " + theToken);
            else if (numvalue = 0) { **//This is where it highlights my error**
                symTable.allocConst(ident, numvalue);
            }

非常感激任何的帮助.

这条线

else if (numvalue = 0) { **//This is where it highlights my error**

缺少一个等号,即

else if (numvalue == 0) { **//This is where it highlights my error**
