indexOf

Returns the index within this string of the first occurrence of the specified substring. The integer returned is the smallest value k such that:


this.toString().startsWith(str, <i>k</i>)

is true.

Return

if the string argument occurs as a substring within this object, then the index of the first character of the first such substring is returned; if it does not occur as a substring, -1 is returned.

Parameters

str

any string.

open fun indexOf(str: String, fromIndex: Int): Int

Returns the index within this string of the first occurrence of the specified substring, starting at the specified index. The integer returned is the smallest value k for which:


    k >= Math.min(fromIndex, this.length()) &&
                  this.toString().startsWith(str, k)

If no such value of k exists, then -1 is returned.

Return

the index within this string of the first occurrence of the specified substring, starting at the specified index.

Parameters

str
