Java Core Exam Part 1

In order the exercises must be completed:

1. SumMatrixValue

   Given a single matrix of ints prints on standard output the sum of all int contained in the matrix

   MATRIX A:
   {
       {2, 4, 6},
       {2, 4, 6},
       {2, 4, 6}
   }
   RESULT: 36
   

2. SumTwoMatrix

   Given two matrix of ints prints on standard output the sum of both matrix

   MATRIX B: 
   {
       {1, 2, 3},
       {1, 2, 3},
       {1, 2, 3}
   }
   
   MATRIX C: 
   {
       {1, 2, 3},
       {1, 2, 3},
       {1, 2, 3}
   }
   
   RESULT:
   {
       {2, 4, 6},
       {2, 4, 6},
       {2, 4, 6}
   }
   

   Result matrix must be printed and formatted as previously shown

3. ReadMatrix Given a string as standard input parse the string into a matrix

   Edit configurations -> set Program arguments

   • args[0] = "{{1,2,3},{1,2,3},{1,2,3}}"

   RESULT: 
   {
       {1, 2, 3},
       {1, 2, 3},
       {1, 2, 3}
   }
   

4. MatrixCombined

   1. Given two string as standard input parse them as matrix,
   2. Then sum both matrix
   3. And pretty print on stdout the result matrix
   4. Then print the sum of matrix result values

   MATRIX A:
       args[0]: "{{1,2,3},{1,2,3},{1,2,3}}"
   MATRIX B:
       args[1]: "{{1,2,3},{1,2,3},{1,2,3}}"
   
   MATRIX B: 
   {
       {1, 2, 3},
       {1, 2, 3},
       {1, 2, 3}
   }
   
   MATRIX C: 
   {
       {1, 2, 3},
       {1, 2, 3},
       {1, 2, 3}
   }
   
   RESULT:
   {
       {2, 4, 6},
       {2, 4, 6},
       {2, 4, 6}
   }
   
   RESULT: 36
