Program:

            /* ............... START ............... */
                
public class JavaStringBuilder {
	public static void main(String[] args) { 
		 
		StringBuilder  string = new StringBuilder ("Welcome To JavaScan.com");
	    System.out.println("string: " + string);
	 
	    System.out.println("substring: " + string.substring(0,10));
	 
	    string = string.insert(5, "insert");
	    System.out.println("insert: " + string);
	 
	    string = string.replace(8,18,"_replace_");
	    System.out.println("replace: " + string);
	 
	    string = string.append("append");
	    System.out.println("append: " + string);
	 
	    System.out.println("indexOf: " + string.indexOf("Scan"));
	 
	    string = string.reverse();
	    System.out.println("reverse: " + string);
	 
	    System.out.println("lastIndexOf: " + string.indexOf("."));
	  } 
}
                /* ............... END ............... */
        

Output

string: Welcome To JavaScan.com
substring: Welcome To
insert: Welcoinsertme To JavaScan.com
replace: Welcoins_replace_avaScan.com
append: Welcoins_replace_avaScan.comappend
indexOf: 20
