java - 我的最后 3 个 if else 语句出现错误

Question

if (annual <= lowincome && aChar == 'S')
    owe = annual * .25;
else if ( annual > lowincome || annual < medincome && aChar == 'S')
    owe = annual * .50;
else if (annual > medincome && Char == 'S')
    owe = annual * .75;
else if (aChar == 'M' && annual <= lowincome)
    owe = annual *.24;
else if(annual > low income || annual < medincome && aChar == 'M')
    owe = annual * .49;
else if(annual > medincome && Char == 'M')
    owe = annual * .74;

我希望用户输入他们是已婚还是单例，然后在找到年收入后进行计算。我收到此错误

Answer 1

if(annual > low income || annual < medincome && aChar == 'M')

应该是

if(annual > lowincome || annual < medincome && aChar == 'M')

低和收入都不会被识别为声明的变量。
