Q44: Java Program to use all the methods defined by string class (substring, indexOf, length, charAt, getchars etc).

class StringMethods{
	public static void main(String args[]){
	    String s = "This is a demo of the getchars method.";
		int start = 10;
		int end = 14;
		char buf[] = new char[end - start];
		s.getChars(start, end, buf, 0);
	
		System.out.println(buf);
		String org = "This is a test. This is, too.";
		String search = "is";
		String sub = "was";
		String result = "";
		int i;
		
		do{
			System.out.println(" ");
			System.out.println(org);
			i = org.indexOf(search);
			if(i != -1){
				result = org.substring(0, i);
				result = result + sub;
				result = result + org.substring(i + search.length());
				org = result;
			}
		}while(i != -1);
	}
}
