這是我的代碼。我需要獲取數組的最小值和最大值,以便我可以獲取範圍,只要輸入數字的最小值爲0,請幫助我。謝謝:)如何獲得數組的最小值,最大值?
final AutoCompleteTextView inputValues = (AutoCompleteTextView) findViewById(R.id.txt_input);
final TextView txtMinimum = (TextView) findViewById(R.id.txtMinimum);
final TextView txtMaximum = (TextView) findViewById(R.id.txtMaximum);
final TextView txtRange = (TextView) findViewById(R.id.txtRange);
Button btncalculate = (Button)findViewById(R.id.btncalculate);
btncalculate.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
String []values = (inputValues.getText().toString().split(","));
int[] convertedValues = new int[values.length];
// calculate for the minimum and maximum number
int min = 0;
int max=0;
min = max = convertedValues[0];
for (int i = 0; i < convertedValues.length; ++i) {
convertedValues[i] =Integer.parseInt(values[i]);
min = Math.min(min, convertedValues[i]);
max = Math.max(max, convertedValues[i]);
}
txtMinimum.setText(Integer.toString(min));
txtMaximum.setText(Integer.toString(max));
// calculate for the range
int range=max - min;
txtRange.setText(Integer.toString(range));
}});
使用Java 8流,可以在一行 –
