Декораторы Java — написание классов в качестве декораторов ⇐ JAVA

[Anonymous]

I learn about decorators, and I wrote the following java classes, used to manipulate matrix (Switching rows, columns, and value multiply):

interface MatrixOperation(){ int[][] apply(int[][] matrix); } class SwitchRows implements MatrixOperation{ int[][] apply(int[][] matrix){ int[][]res=new int[2][2]; res[0]=matrix[1]; res[1]=matrix[0]; return res; } } class SwitchCols implements MatrixOperation{ int[][] apply(int[][] matrix){ int[][]res=new int[2][2]; for(int i=0;i
