What is the correct regex to accomplish string split in java? -


i have string "50[=]test item" want split in java using string.split "50" , "test item". correct regex accomplish that.

any appreciated.

you need escape [, while splitting, special character in regex. need escape [ because starts character class. no need escape ]:

arrays.tostring("50[=]test item".split("\\[=]"));

will give you: 

[50, test item]
