How can I convert the following code to switch statement?
String x = "user input";
if (x.contains("A")) {
//condition A;
} else if (x.contains("B")) {
//condition B;
} else if(x.contains("C")) {
//condition C;
} else {
//condition D;
}
also HashMap:
String SomeString = "gtgtdddgtgtg";
Map<String, Integer> items = new HashMap<>();
items.put("aaa", 0);
items.put("bbb", 1);
items.put("ccc", 2);
items.put("ddd", 2);
for (Map.Entry<String, Integer> item : items.entrySet()) {
if (SomeString.contains(item.getKey())) {
switch (item.getValue()) {
case 0:
System.out.println("do aaa");
break;
case 1:
System.out.println("do bbb");
break;
case 2:
System.out.println("do ccc&ddd");
break;
}
break;
}
}
