文章分段的代码
int int2 = comment.length();
StringBuffer StringBuffer3 = new StringBuffer();
int int4;
for( int4 = 0; int4 < int2; ++int4 )
{
char char5 = comment.charAt( int4 );
switch( char5 )
{
case 62:
StringBuffer3.append( ">" );
break;
case 60:
StringBuffer3.append( "<" );
break;
case 38:
StringBuffer3.append( "&" );
break;
case 32:
StringBuffer3.append( " " );
break;
case 10:
StringBuffer3.append( "<BR>" );
break;
default:
StringBuffer3.append( char5 );
break;
case 13:
break;
}
}
comment=StringBuffer3.toString();
