Wrong when using split in Java

I use split in Java like this

String str = "Bx=1946^Cx=1043423";
String[] parts = str.split("^");
for (String part : parts)
    System.out.println(part);

But it turns out there is only one element in parts array after splitting, so if I want to use "^" as delimiter, what should I write?

Thanks

Use

str.split(Pattern.quote("^"));

instead of

str.split("^");

Pattern.quote() works in case of splitting with multiple symbols too. For example, we can use str.split(Pattern.quote("^^^^")); instead of adding too many special characters like str.split("\\^\\^\\^\\^").

You need to escape the^, which has a special meaning in regex (start of word, line and others):

String str = "Bx=1946^Cx=1043423";
String[] parts = str.split("\\^");
for (String part : parts)
    System.out.println(part);

The output will be:

Bx=1946
Cx=1043423
