The required parameter of the split method is a regular expression, and | is a special symbol in the regular expression, which needs to be escaped
public static void main(String[] args) {
// TODO Auto-generated method stub
String [] b = "a |b|c".split("\\|");
System.out.println(b[0]);
System.out.println(b[1]);
System.out.println(b[2]) ;
}
split() | returns wrong result
