java - split() function for '$' not working -

-

this question has answer here:

i'm doing simple code 

string splitstring = "122$23$56$rt"; for(int i=0;i<splitstring.split("$").length;i++){    system.out.println("i got :: "+splitstring.split("$")[i]); }

when split 

splitstring.split("$")

it giving me output [122$23$56$rt]

why not splinting on '$'?

string.split() takes in regex argument , $ metacharacter in java regex api. therefore, need escape it:

string splitstring = "122$23$56$rt"; for(int i=0;i<splitstring.split("\\$").length;i++){    system.out.println("i got :: "+splitstring.split("\\$")[i]); }

other metacharacters supported java regex api are: <([{\^-=!|]})?*+.>
