class toStringTest{
	public static void main(String args[]){
		StringBuffer sb= new StringBuffer("my name is Martin");
		int len = sb.length();
		String a = String.valueOf(len);
		String name = sb. toString ( );
		String s ="111";
		int b = Integer.parseInt(s)*2; 
		Float c = Float.valueOf(s); 
		System.out.println("int b ="+ String.valueOf(b));
		System.out.println("float c ="+ String.valueOf(c));
		System.out.println("length="+a);
		System.out.println("what's your name?  "+name);
