Answer 1

Explanation:

class Index

{

public static void main (String args [])

{

String str="kunal_ Kashyap";

System.out.println(str.lastIndexOf(" ")+1);

}

}

So,the java statement is:

System.out.println(str.lastIndexOf(" ")+1);

Working:

*the function lastIndexOf() returns the index of last position of space in the string.but,we need to add 1 to it as index starts from 0.
