The java string getChars() method copies characters from the given string into the destination character array.
Syntax:
public void getChars(int srhStartIndex, int srhEndIndex, char[] destArray, int destStartIndex) Parameters: srhStartIndex : Index of the first character in the string to copy. srhEndIndex : Index after the last character in the string to copy. destArray : Destination array where chars will get copied. destStartIndex : Index in the array starting from where the chars will be pushed into the array. Return: It does not return any value.
Exception: StringIndexOutOfBoundsException – If srhStartIndex, srhEndIndex are not in proper range.
Example : To show working of getChars() method
java
// Java program to demonstrate // working of getChars() method class Gfg1 {
public static void main(String args[])
{
String str = "Welcome! to GeeksforGeeks";
char [] destArray = new char [ 20 ];
try {
str.getChars( 12 , 25 , destArray, 0 );
System.out.println(destArray);
}
catch (Exception ex) {
System.out.println(ex);
}
}
} |
Output:
GeeksforGeeks
java
// Java program to demonstrate // exception condition in // working of getChars() method class Gfg2 {
public static void main(String args[])
{
String str = "Welcome! to GeeksforGeeks";
char [] destArray = new char [ 20 ];
try {
// Starting index 0 and ending index 24
str.getChars( 12 , 26 , destArray, 0 );
System.out.println(destArray);
}
catch (Exception ex) {
System.out.println(ex);
}
}
} |
Output:
java.lang.StringIndexOutOfBoundsException: String index out of range: 26
