所以我正在擺弄java，并遇到了我試圖編寫的一些代碼的問題。我創(chuàng)建了一個類，LogicGate在該類中調(diào)用有方法將實例的狀態(tài)設(shè)置LogicGate為 true 或 false。LogicGate只有一個屬性及其布爾值 true 或 false。所有方法似乎都有效，但只有一個（稱為 not()），我將布爾值更改為 false（如果 true）和 true（如果 false）。該代碼第一次將值從 true 更改為 false，但第二次它似乎忽略了 if 語句。//Mainpublic class main {    public static void main(String[] args) {        LogicGate logicGate = new LogicGate(true);        System.out.println(logicGate.state());        System.out.println("");        logicGate.not(logicGate);        System.out.println("");        System.out.println(logicGate.state());        System.out.println("");        logicGate.not(logicGate);    }}//Class Logicgatepublic class LogicGate {    //The attribute for the for the object    private boolean state;    //Creating the constructor for the object logic gate     public LogicGate(boolean logicGateState) {        state = logicGateState;    }    //This method changes the state of the Logic Gate    public  void not(LogicGate obj) {        //Saving the current state of the logic gate        boolean currentState = obj.state();        System.out.println("....." + currentState);        //Checks the state of the object instance and changes it accordingly        if(currentState = true) {            obj.negate(obj);            System.out.println("The state has changed to: " + obj.state() + " Should be false");        }        else if(currentState = false) {                 obj.set(obj);            System.out.println("The state has changed to: " + obj.state() + " Should be true");        }    }    //Sets the state of the object boolean variable to true     public  void set(LogicGate obj) {        obj.setState(true);    }    //Sets the state of the object boolean variable to false     public  void negate(LogicGate obj) {         obj.setState(false);    }    //This method will return the state of the object    //it can be either true or false     public boolean state() {        return state;    }每次調(diào)用 not 方法時，布爾值都應(yīng)該改變。代碼的最后一行應(yīng)該說The state has changed to: true Should be true。
