<%!
public void str_repeat(String str2,int num){
     int i;String FINAL="";
     for(i=0;i<num;i++)FINAL=FINAL+str2;

My Code Now Is As Follows :
<%@ page import = "java.io.*"%>
<%!
public void str_repeat(String str2,int num, JspWriter out){
     int i;String FINAL="";
     for(i=0;i<num;i++)FINAL=FINAL+str2;
      out.print(FINAL);
%>
<%
str_repeat("SOMETHING",2, out);
%> and it gives the following error :
org.apache.jasper.JasperException: Unable to compile class for JSP:
An error occurred at line: 17 in the jsp file: /index.jsp
Unhandled exception type IOException
14: public void str_repeat(String str2,int num, JspWriter out){
15:      int i;String FINAL="";
16:      for(i=0;i<num;i++)FINAL=FINAL+str2;
17:       out.print(FINAL);
18: }
