what is the meaning of for loop in java
For loop In computer science, a for-loop (or simply for loop) is a control flow statement for specifying iteration, which allows code to be executed repeatedly. The syntax of a for-loop is based on the heritage of the language and the prior programming languages it borrowed from, so programming languages that are descendants of or offshoots of a language that originally provided an iterator will often use the same keyword to name an iterator, e.g., descendants of ALGOL use "for", while descendants of Fortran use "do." There are other possibilities, for example COBOL which uses "PERFORM VARYING".
Software bug A software bug is an error, flaw, failure or fault in a computer program or system that causes it to produce an incorrect or unexpected result, or to behave in unintended ways. The process of fixing bugs is termed "debugging" and often uses formal techniques or tools to pinpoint bugs, and since the 1950s, some computer systems have been designed to also deter, detect or auto-correct various computer bugs during operations.
