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

Question

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?

Answer 1

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);

Answer 2

final String str = "Millett Angle-Loc Weaver Extension 1 inch Rings, Black, Medium, Front/Rear Exte";

System.out.printf("%s\n", str.substring(0, str.lastIndexOf(' ')));

This prints:

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