How To Make Void That Prints Something In JSP
hi Everyone I'm Very New To Java & JSP I'm Expert In PHP , Anyway . .
I want A Code like The Following Print Something Out :
<%@ pageimport ="java.io.*"%>
<%!
publicvoid str_repeat(String str2,int num){
int i;String FINAL="";
for(i=0;i<num;i++)FINAL=FINAL+str2;
System.out.print(FINAL);
}
%>
<%
str_repeat("SOMETHING",2);
%>
And Please I don't Want Anyone to Come UP with A Function That Makes The String Repeat (( I Wan To Learn How To Make A Void That Outputs Something )) And Not A Function . .
notice : The Above Code Gives Nothing At All And When I Use
out.print
Instead Of System.out.print
It Gives Error

The method str_repeat does not have access to the implicit variable "out" and as such can not do output all on its own.
One solution would be pass the JSPWriter to the method to let it do output.
ie
<%@ 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);
%>

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: }
