public class Construction {

  public static void main(String a[]){

    char chars1[]={'a','b','c'};
    char chars2[]={'e','f','g','h','j'};
    byte ascii[]={120,121,122};
    String s1=new String(chars1);
    String s2=new String(chars2,0,5);
    String s3=new String(ascii,0,3);
    String s4="helloworld-well !";
    String s5="w";

    System.out.println("String s1="+s1);
    System.out.println("String s2="+s2);
    System.out.println("String s3="+s3);
    System.out.println("String s4="+" \" "+s4+" \" ");
    System.out.println("s4.length="+s4.length());

    System.out.println(s4.charAt(0));
    System.out.println("s4.indexOf(100)="+s4.indexOf(100));
    System.out.println("s4.indexOf(w,7)="+s4.indexOf("w",7));
    System.out.println("s4.lastindexOf(world)="+s4.lastIndexOf("world"));
    System.out.println();
