使用分配给char数组的charAt（）函数会抛出错误

Question

I'm trying to save string in to a character array using the below code & im getting this error: Type mismatch: cannot convert from char to char[]

Below is the code

public class ExCaluculator{
char[] swi=new char[10];
String San="hello world" ;
int samsu ;
public void excal(){

for(samsu=0;samsu>San.length();samsu++)
{
    swi=San.charAt(samsu);
}   
}
}

Also please suggest me any other methods to do the same

Answer 1

ou have to assign the value to an element of the array:

public class ExCaluculator{
char[] swi=new char[10];
String San="hello world" ;
int samsu ;
public void excal(){

for(samsu=0;samsu>2;samsu++)
{
    swi[samsu]=San.charAt(samsu);
}   
}
}

Answer 2

You can't assign a char to char[] , array is subscript based. use something like

swi[0] = San.charAt(samsu);

Answer 3

Array must be accessed with an index and you need a change in condition of for statement.

for(samsu=0;samsu<San.length();samsu++)
{
    swi[samsu]=San.charAt(samsu);
}   

Also you have to increase the array size to 11 ( char[] swi = new char[11]; ) in order to avoid ArrayIndexOutOfBoundsException .

Or Simply you can use

char[] xyz = san.toCharArray();
