please help with this programming homework. language is java

nplement the following methods concerning 2-D arrays: 1. double min(double[]] numss) - that retums the min value of a 2-D double array 2. double[] minOfRow(double[]] numss) - that returns the min value of each row ( 1U dimension) of a 2-D double array 3. double[] minOfCol(double[]] numss) - that returns min value of each column ( 2ad dimension) of a 2-D double array 4. double[]]] add(double[1]] numss1, double[][] numss2) - that adds two 2-D double arrays together; returns a new array, - Eg. numss1: {{1,2,3},{4, 5}}, numss2: {{1,2},{3,4,5},{6,7}}, returns {{2,4,3},{7,9,5},{6,7}} 5. double[]] deleteRow(double[]]] numss, int idx) - that deletes a row (1" dimension) from a 2-D double array. - Returns a new 2-D array 6. double[]] appendArray(double[][] numss1, double[][] numss2) - that appends a 2-D double array under another 2D double array; - returns a new 2-D array. - E.g. numssl: {{1,2},{3,4,5}, {6}}, numss2: {{7},{8,9}}, returns {{1, 2}.{3,4,5},{6},{7},{8,9}} 7. double[][] expandArray(double[]] numss1, double[]]] numss2) - that appends a 2-D double array at the right of another 2-D double array. - Eg numss1: {{1,2},{3,4,5}, {6}}, numss2: {{7},{8,9}} + returns {{1,2, 7},{3,4,5,8,9},{6}} 8. double[][] transposeMatrix(double[]] numss) to flip the row and the collom of a matrix - E.g. numss: {{1,2,3},{4,5,6}}, returns {{1, 4},{2,5},{3,6}}
