Question

Public class my{
Public Static void main(String []args){
String g= “Hello i love java”;
Int start=2;
Int end=9;
Char s[ ]=new char[end-start];
g.getchars(start,end,s,0);
}}
Output is: llo i l

Iam not understanding why ?

Answer 1

s is an array of 7 characters.
with g.getchars() method, s is assigned to the characters of g index ranging from start to end.

in the output first 'l' corresponds to the char with index 2 in g, same way, last 'l' corresponds to the char with index 8.

Answer 2

it copies chars form position 2 to 9 (except 9)
String g = "He llo I l ove java";
// 01 2345678 90123456

public class my {
public static void main(String []args){
String g = "Hello I love java";
int start =2;
int end =9;
char[] s = new char[end-start];
g.getChars(start, end, s, 0);

System.out.println( s );
}
}

Answer 3

from g.getchars(start,end,s,0);
how we get llo i l ??

Answer 4

Indian explanation is already given by @zemiak.

From string g, it copies charecters from start index (2) to end-1 (9-1=8, end not inclusive) index.. into the s charecter array...
