high-school I did Pascal, taught myself Delphi so that I could actually build useful stuff with Pascal.
taught myself BASIC so that I could understand example code in Basic and actually use it in Delphi
varsity I had to use C, C++, Matlab, Assembler, Python, VHDL and some other less known languages - Java we only used in two or three courses either in third or fourth year and we didn't need to know much Java to get by (since the courses could've been in any language). We were never taught any languages, we just got assignments and getting up to scratch with the language was your own problem. Sometimes the assignments stated, use any language or use this language (often not a language you've worked with before)
First job I wrote an entire system in PHP, didn't know PHP before I started, second job, perl developer, didn't know perl before I started, third job Python developer, just knew enough Python to get the get the job, only 4 years after I worked in PHP, perl and Python did I work professionally in Java
So long story short, was never taught any languages other than Pascal, the principles remained the same throughout every language, so it didn't matter (for me) what language I was taught in school.
