2 dimensional array java

Multi-dimensional array into one-dimensional array, multi-dimensional array dimension Convert a multi-dimensional array into a one-

For example, the following two-dimensional array is each row, each column is an ascending sort. Returns True if the number 7 is found in this array, or FALSE if you look for an array of 5, because the array does not contain the number. 1
