Ok, the String class is a very important tool in java. Make yourself famaliar with it.
Go to this Weblink to revise some of its properties.

Your code should be simliar to this....

public static void main(String[] args) 
  {
    /*1) Find the 5th caracter in the string " RUSTIN BOND" 
        2) Find the index of character "K"in string "KANSAS".
        3) Convert the string "hello world"to uppercase.
        4) Replace character 'h'with 'b'in the string"humble */

    String no1 = "RUSTIN BOND";
    String no2 = "KANSAS";
    String no3 = "hello world";
    String no4 = "humble";

    //print out the results

    //remember java indicies start at 0
    System.out.println("\nCurrent String: " + no1);
    System.out.println("The 5th character: " + no1.charAt(4));

    //remember java indicies start at 0
    System.out.println("\nCurrent String: " + no2);
    System.out.println("The index of character k: " + (no2.indexOf("K") + 1) );

    System.out.println("\nCurrent String: " + no3);
    System.out.println("Convert string to uppercase: " + no3.toUpperCase());

    System.out.println("\nCurrent String: " + no4);
    System.out.println("Replace character h with b: " + no4.replace('h', 'b'));
  }
