print array in the log cat android

android, android-logcat, eclipse, java

Solution

You can use `Arrays.toString`

Log.d("this is my array", "arr: " + Arrays.toString(arr));
// or
System.out.println("arr: " + Arrays.toString(arr));

Or, if your array is multidimensional, use Arrays.deepToString()

String[][] x = new String[][] {
    new String[] { "foo", "bar" },
    new String[] { "bazz" }
};
Log.d("this is my deep array", "deep arr: " + Arrays.deepToString(x));
// or
System.out.println("deep arr: " + Arrays.deepToString(x));
// will output: [[foo, bar], [bazz]]

Problem

How can I print the arr variable in the log to see the results of the array thanks, ``` public void onClick(View v) { if(v.getId()==R.id.buttonone) { genrandom grandom =new genrandom(); int[] arr=new int[50]; arr = new gen_random_number().genrandom(arr, yourXvalue); } } ```
