Question

I begin with java and I’m searching for how to create an array 2d of strings :
my array 2d should contains :

10 20 "OK"
5  30 "KO"
20 100 "NA"
10 60  "OK"

String[][] matrix = new String[i][j];
for(r=0;i<matrix.length; r++) {
 for (int c=0; c<matrix [r].length; c++) {
     System.out.print("10 " + matrix [r][c]);
 }

What Florin said, but with simplified for-loop:

String [][] matrix =  { {"10","20","OK"}, {"5","30","KO"}, {"20","100","NA"}, {"10","60","OK"} };

for (String [] line : matrix) {
    for (String s: line) {
        System.out.print ("10 " + s);
    }
}
