Java: Getting a substring from a string ending before a particular character

I have a String

Millett Angle-Loc Weaver Extension 1 inch Rings, Black, Medium, Front/Rear Exte

I would like to extract "Millett Angle-Loc Weaver Extension 1 inch Rings, Black, Medium, Front/Rear" from this String, ie, the substring before the last " "(space/blank) (or first from right).

Could someone please provide some help?

Solution

  • Assuming your input String is str, try this. It should do it.

    int i = str.lastIndexOf(' ');
String str1 = i >= 0 ? str.substring(0, i) : "";
String str2 = str.substring(i + 1);
System.out.println(str1);   
System.out.println(str2);
