This is my class Debugger. Can anyone try and run it and see whens wrong? Ive spent hours on it already. :(

public class Debugger {

private String codeToDebug = "";

public Debugger(String code) {
    codeToDebug = code;
}

    boolean isInside = false;

    int stored = 0;
    String[] codeArray = codeToDebug.split("");

    try {
        int i = 0;
        while(i<codeArray.length) {
            if(codeArray[i].equals("}")) {
                isInside = false;
            }
            if(isInside && !codeArray[i].equals(" ")) {
                boolean methodFound = false;
                String method = "";
                int c = i;
                while(!methodFound) {
                    method += codeArray[c];

                    } else {

                    }
                }
                methodStorage.add(stored, method);

                System.out.println(methodStorage.get(stored));
                stored++;

                boolean stillInside = true;
                int skip = i;
