java - KeyTyped 事件 - 无法读取字符串的最后一个字符

Question

所以我一直在研究这个密码强度检查器，并在输入密码时向用户提供分数分解的视觉反馈，我使用 KeyTyped 事件，然后分析字符串并最终开始给出分数达到最小长度。以下是分析的一部分：

if (in.matches("[a-z]+")){
    lowerPenalty = -15;
}
if (in.matches("[0-9]+")){
    numPenalty = -15;
}

for(int i=0;i<inLen;i++){
    if ((in.charAt(i) + "").matches("[A-Z]")){   
        upperCounter++;
        upperBonus = upperBonus + 4; 
    }

但是，当我运行程序时，它不考虑用户输入的密码的最后一个字符，因此相应的计数器不会增加。这是屏幕截图：

正如您在上面的屏幕截图中看到的，Number Bonus 行中的 numCounter 仍然是 '1' 而不是 '2'。我试过使用 KeyPressed 事件，但问题仍然存在。

请帮忙。

根据要求，这是 keyListener 代码：

input.addKeyListener(new KeyAdapter(){
        @Override
        public void keyTyped(KeyEvent e1){

            if ((int)e1.getKeyChar() == 8){
                count = -1;
                baseScore = 0;
                lenBonus = 0;
                upperBonus = 0;
                upperCounter = 0;
                numBonus = 0;
                numCounter = 0;
                symBonus = 0;
                symCounter = 0;
                comBonus = 0;
                lowerPenalty = 0;
                numPenalty = 0;
                comBonus = 0;
                totalScore = 0;
                input.setText("");
                strength_lbl.setText("Enter a random password");
                strength_lbl.setBackground(Color.LIGHT_GRAY);

            }

            count++;
            Counter.setText(count+"");
            analyzeStr(input.getText());

            baseScore_txt.setText(baseScore+""  );
            lowerPen_txt.setText(lowerPenalty+"");
            numonlyPen_txt.setText(numPenalty+"");
            upperBonus_txt.setText(upperBonus+" [" + (upperCounter) + "x4]");
            numBonus_txt.setText(numBonus+" [" + numCounter + "x5]");
            symBonus_txt.setText(symBonus+" [" + symCounter + "x5]");
            comBonus_txt.setText(comBonus+"");
            totalScore = baseScore + lenBonus + upperBonus + numBonus + symBonus + comBonus + lowerPenalty + numPenalty;
            totalScore_txt.setText(totalScore+"");  

            if (totalScore>=1 && totalScore<50){
                strength_lbl.setText("Weak!");
                strength_lbl.setBackground(Color.red);
            }
            if (totalScore>=50 && totalScore<75){
                strength_lbl.setText("Average!");
                strength_lbl.setBackground(Color.orange);
            }
            if (totalScore>=75 && totalScore<100    ){
                strength_lbl.setText("Strong!");
                strength_lbl.setBackground(Color.cyan);
            }
            if (totalScore>=100){
                strength_lbl.setText("Secure!");
                strength_lbl.setBackground(Color.green);
            }


        }
    });

根据要求，这是 analyzeString 方法：

    public void analyzeStr(String str){

    String in = input.getText();
    int inLen = input.getText().length();

    if (count == 1){
        strength_lbl.setBackground(Color.RED);
        strength_lbl.setText("At least 8 characters please!");
    }

    if  (input.getText().length()<8){
        lengthBonus_txt.setText("0");
    }
    else{
        lengthBonus_txt.setText(lenBonus +" [" + (count-8) + "x3]");
    }

    if (count==8){

        baseScore = 50;


        if (in.matches("[a-z]+")){
            lowerPenalty = -15;
        }

        if (in.matches("[0-9]+")){
            numPenalty = -15;
        }

        for(int i=0;i<inLen;i++){
            if ((in.charAt(i) + "").matches("[A-Z]")){
                upperCounter++;
                upperBonus = upperBonus + 4; 
            }

            if ((in.charAt(i) + "").matches("[0-9]")){
                numCounter++;
                numBonus = numBonus + 5;
            }

            if ((in.charAt(i) + "").matches("[!,@,#,$,%,^,&,*,?,_,~]")){
                symCounter++;
                symBonus = symBonus + 5;
            }

        }

    }

    if (count>8){
        lenBonus = lenBonus + 3;
        lengthBonus_txt.setText(lenBonus+" [" + (inLen-7) + "x3]");

        if ((in.charAt(inLen-1) + "").matches("[A-Z]")){
            upperCounter++;
            upperBonus = upperBonus + 4; 
        }

        if ((in.charAt(inLen-1) + "").matches("[0-9]")){
            numCounter++;
            numBonus = numBonus + 5;
        }   

        if ((in.charAt(inLen-1) + "").matches("[!,@,#,$,%,^,&,*,?,_,~]")){
            symCounter++;
            symBonus = symBonus + 5;
        }
    }

    if (count>=8){
        if (in.matches("[A-Z][0-9][!,@,#,$,%,^,&,*,?,_,~]")){
            comBonus = 25;
        }
        if (in.matches("[0-9][A-Z][!,@,#,$,%,^,&,*,?,_,~]")){
            comBonus = 25;
        }
        if (in.matches("[!,@,#,$,%,^,&,*,?,_,~][0-9][A-Z]")){
            comBonus = 25;
        }
        if (in.matches("[!,@,#,$,%,^,&,*,?,_,~][A-Z][0-9]")){
            comBonus = 25;
        }
        if (in.matches("[!,@,#,$,%,^,&,*,?,_,~][A-Z][0-9]")){
            comBonus = 25;
        }
        if (in.matches("[A-Z][!,@,#,$,%,^,&,*,?,_,~][0-9]")){
            comBonus = 25;
        }
        if (in.matches("[0-9][!,@,#,$,%,^,&,*,?,_,~][A-Z]")){
            comBonus = 25;
        }
    }
