被这个数组搞晕了
两个数组：
String[] colrst={"NAME","YEAR","MONTH"};
String[][] result={{"name1","name2","name3"},{"2011Y","2012Y"},{"1M","2M","3M"}};
要得到：
NAME=name1 and YEAR=2011Y and MONTH=1M
NAME=name1 and YEAR=2011Y and MONTH=2M
NAME=name1 and YEAR=2011Y and MONTH=3M
NAME=name1 and YEAR=2012Y and MONTH=1M
NAME=name1 and YEAR=2012Y and MONTH=2M
NAME=name1 and YEAR=2012Y and MONTH=3M
NAME=name2 and YEAR=2011Y and MONTH=1M
NAME=name2 and YEAR=2011Y and MONTH=2M
NAME=name2 and YEAR=2011Y and MONTH=3M
NAME=name2 and YEAR=2012Y and MONTH=1M
NAME=name2 and YEAR=2012Y and MONTH=2M
NAME=name2 and YEAR=2012Y and MONTH=3M
NAME=name3 and YEAR=2011Y and MONTH=1M
NAME=name3 and YEAR=2011Y and MONTH=2M
NAME=name3 and YEAR=2011Y and MONTH=3M
NAME=name3 and YEAR=2012Y and MONTH=1M
NAME=name3 and YEAR=2012Y and MONTH=2M
NAME=name3 and YEAR=2012Y and MONTH=3M
