Title Body

I want to know how can I use the variable a[i][j] in the method Scores() to use it in the methods MD() and sumD() in the following code: In my code, the methods MD() and sumD() can't get the result. public class Test3 { public void Scores() { double[][] a= new double[3][5]; int i,j; for(i=0; i<3; i++ ){ for(j=0; j<5; j++){ a[i][j]= (double) Math.random(); System.out.println("a[" + i + "][" + j + "] = " +a[i][j]); } } } public void MD(){ double[][] b =new double[3][5]; int [] m = new int[5]; int i,j; //double[][] a= new double[3][5]; for(j= 0; j<5; j++) for(i=0 ; i<3 ; i++) { b[i][j]=0.0; if(a[i][j]>0.0) m[j]++; } for(j= 0; j<5; j++){ for(i=0 ; i<3 ; i++) { if(a[i][j] > 0.0){ b[i][j]=a[i][j]*m[j]; System.out.println("b[" + i + "][" + j + "] = " + b[i][j]); } } } } public void sumD(){ int i,j,n; double[] sum= new double[3]; double[] k= new double[3]; //double[][] a= new double[3][5]; for(i=0; i<3; i++){ n=0; sum[i]=0.0; for(j=0; j<5; j++){ if(a[i][j]>0.0){ sum[i] += (a[i][j])*2; n++; } } k[i]=sum[i]/n; System.out.println("k[" + i + "] = " + k[i]); } } public static void main(String[] args){ Test3 print= new Test3(); print.Scores(); print.MD(); print.sumD(); } }
