我的问题是如何更改if-else语句来切换case语句,我做了一些工作,它在netbean中包含错误:
if(result.length <= 2){
if ((result[0].equals("UC"))||(result[0].equals("uc"))){
fix = "UC";
}
else if ((result[0].equals("LC"))||(result[0].equals("lc"))){
fix = "LC";
}
else
fix = "error";
}else
fix = "length";

试试这个
switch (result[0]) {
case "UC":
case "uc":
fix = "UC";
break;
case "LC":
case "lc":
fix = "LC";
break;
default:
fix = "error";
}

if(result.length <= 2){
switch(result[0]){
case "UC":
case "uc":
fix = "UC";
break;
case "LC":
case "lc":
fix = "LC";
break;
default:
fix = "error";
break;
}
}
else
fix = "length";

另一种解决方案:
switch (Boolean.toString(result.length <= 2)) {
case "true":
switch (result[0]) {
case "UC":
case "uc":
fix = "UC";
break;
case "LC":
case "lc":
fix = "LC";
break;
default:
fix = "error";
}
break;
default:
fix = "length";
}

您可以使用以下内容:
if(result.length <= 2)
{
switch(result[0])
{
case "UC":
fix = "UC";
break;
case "uc":
fix = "uc";
break;
case "UC":
fix = "LC";
break;
case "uc":
fix = "lc";
break;
default:
fix = "error";
}
}
else
{
fix = "length";
}
