help with storing characters in a string on an interval?

[googleplexx]

what I want to do is dump the characters in a string into a new string based on an interval say I have a

String blah = "asksa123sbjdskc";

all i want is abc (ie every fifth character)

this is my attempt with 236 characters of junk inbetween the chars i want.

String input = "j4o8xcntu2q2o43d0xg9s3ubt5dwxm0llha8acnr6gyw54i9h7e4ay6117kalgygrkm50bg4r7v97d4h9yp4kmyh0dmc6q3t9g2xi1pnpmbfkvs5xa867t7whj3kecqboeukvc0cn9ayfl780gg41y16f90gh12xbuamb1q8bh85p4wijjb1jjkm421oyorueig9gvnwcigngg4sf8nplmp3gtdjjrixyp3eou677jwqefbiemohmfxe0sw3gh6axr4qcopauf7xc25dmmx4yv1x0jxq2517sag288rlt7aqpk2tvccoxsgsmic66rye8eso7fxlh1nl5egnu99ydrrdb6ojafodewxqiw08dqfn0v7wrh8bl67anart7cld2jve1i6lxqfy02y78l00e9tqsse4xit7w4tvw3t6tjwknyv13a9nio68byyosbd5ywbgkjnw1ihw8w8alh845akd5rpuyuno8ljjyvbtyns9oj6r7vkrbowf7qabvk7cndo2cnskapndpcxvgk2io0s1gp2genwxmgcjkcc0v9vl4wgahtdkknv9egoqd9uj97b3sx71xsmcrlct5cu20fl0l5icpc8ttuufrbyuguct15cmgv48sat94364hcj47ojndj4ayq0iqn7dw2kqpe4722fkp297p7m3loxoqwotact0l0b3yg7k25c95rjkxsacnpufwt4a377le0r1f49jfbmla6n9v6jdvdpvmt1imo17qnmjkwlj0qf85egbrm4fdsfawka2dsqdkjv44o8ksdbat2d4nfaps5t9v8f7fgs4j4kf7seg61w62u6c6ectju53xh9j2w44b7wlye6br9ivx4j1hgw8n254u8lywkxcjkiftiheoecrqywv2y1al7ebfa3tdu918c54j65ce857w55pmhfc4v858e5mbc4pg4njts43nbetsiks6is6991glonnk4dot2o61yb5eehfxpjjyx694xaqk9v8nnl14tsik36n823g4k5o0sqxyfl0f5lcw01fpugrd4rqhead06l6wrara892wuvbys81831e8fajrhc7gwbouc9b6brp7huoklnf690bqmsqm3jm23v3mexw6dkv5q1uwojtmsu9uibkgme8jobyrwxo4ld32paxjpoa1h3l793ru95yqhrot8y1xfe72dkrw4dp6iql504yvxd7usb9d4vvkgmjvsicu1cl06obf5wc055c3coqdpsn260n1r7vrfe6fr420ga2f6iq2ckkypa3a5k9xu6e8g0bilwk99rnt7da4shv6tej1pqennpqosry9qm0a9g0mcwi3wsjwjxshcfms1u7nconeacdyglwhga9ekb7f3sexhacr8osh948b7qkklo96wm08r1jwrr2ybfe9mta4h5aoh3hcbop5n0364mc1fijfo1d4vi909oyiubsoaqnkha7xhi7i1mt1ab1977ebn7h3nkaiqxa09es0uari4qwksw5ltbc4wtsbfe5fdt1kkwmu138d79ecal1c3hck2m2nb3bu21f5ynp5g3uynq41yg98f3q9y78cixahtwg1g4mc4o9gyqclx7wipctbga1p5jtnyodlx5brgr3b5tdntvyh4sc64x616i4hhrqd3vyslljqt8v4rwvuytnr72lrdrc2sr9m8gejdu6fgak5dg1d9mwaryp1vqlyjlu40r9qpi1lrm7wj63vdu8qnoh65dabd4r35l6y3r2el1n7h6ej9mb1flpqwejvij78s0e76ydh7irwrss3jdnfcmau4ci4vjra2u8u3456w6rw75vmef4me9g31xhnffdhfy9a7koqyd6dtgern1ajj2o9m1dcr57fotbe05vwm4m810xw28jlsa2ppfe831s71sc6k77sqdmet45qkqw43iulrd8bguaeo8w1ub8ipneq02l6ree63fkge2k5309w0gtqa5l80j8q6ewuo3hngy91241vlm8v9ospothr0xjd0ihk8v3849ir30v3sg4vnyvsfy528s9ox6e0vl2wpge2ytbispseiddhp1e1etgg84s4mnt2lrgo6rxctf4mlgddx1drm5pua6ihvag9lr3oxai8h091n765wcggx5hbkxfpx3urrkvb6ky4fe40nsr6exfnbyi3wbp5l9ks7qafqwd7uferfl415m5xn3c4nsc90taj7lu8xwdb3fc6cu5vwph0uqe0f53tkspylvhewohsbjlgaon0pf2dexga45fs77t3suo1hnmo9q2h04cio06isd2xt30bdldh9vbmf0264b2nm83nenfdmdygl1dw51v3i9l1vbh1qamojtdy96c5dkb2t7s0aq4r013i05mqd0d6th1409e97t5f11ieu4jprqpalpj9of4bancmyv9fcn8lpffr0yi9xl76afo4734wuixy1fxleed9wbom9wqtka7ht1c87vpk0f6dgc8kqg6yfurqxwmochrytxksxru5tt83d264jol73hthvwhgo4ya7671pj4mnha9ew26r4pub9g8iuaqax4r6oe10m38l1kcy9hatpwm9eo66riysvdpkar930dyrls4jf7w99j3xqv45nccjqpgtsvt2gbh8ix8kqy62q790orh0ygu8raldcld2qxtpjlsoe5fx9ad4t7f3h8vs37bdotkgxj6gylawasc1ofeak29u45qy71neyeg3ib6628dl7vkqidly5sf00ifeu3fsys8m2uuq78p5e3ayq97bydsj64x96nm9s1he8so2e6t4bn519b28chjfo70paiyeo0m75oy2up1jatph87st89ay8ymsxtyh251olt4c31vcfgnngry82pxt28aa44qrech1cy5sno45tyxt48kowvurvftgx5h7nnvq311k2dndga1pb4e3l0s2y6lw859fol11bdyon4j56fjtao7ub1jkl3qyqec86xmviwgf8cnu81qw0pt990jy4fqhgxhhw001osg7f1yt4pdm6ii1x8072s2hr14hcay43j9pu5nee6hbd3l484q8aq62pcfxi9fb605a9ycs67xmbfnbs7y36xc6gt7tkx92a3p99ju4eh2ia5fyxq6p1tbdq2mveg2dku8k89o0x3eix9jaotioqb7vnffrt5dgb9i0tk2w3fmqvfc35ny8jd823l8cchpvgnlk7r2x0198suu1hcfp403kga9ho1r1b44qjekgxvyfvugucp0ipweu0fb45tpueq5s2theca8viu1r9d9xo3muxnxmmwuqurg9fw22ekq372d1xk10m6w2tfsygb0hfcxpqpynfcd8c6m3gi25x274o3s5vfpy5nq0e0imm3df048phffrva2v9c1168r6rtwpy5gkasq09jv8kflmy8214sdfuch03ohfji4m739ps6q4960ooitmhs5lf9pc57l0snka98vsu7sf0yh4vuqqbbr416q5tam6y4y87x6dskhjb09elguqv43roynoknm8f13hov1y6";

but I'm not getting what i should be.
thanks for any help or insights

Your code is starting on character 0, not 235.
