java取数组最大值最小值_java – 如何获得数组的最小值,最大值？

参见英文答案 >

Finding the max/min value in an array of primitives using Java                                    15个

这是我的代码.我需要得到我的数组的最小值,最大值,以便能够得到范围,每当我输入数字时,最小值为0.请帮助我.谢谢：)

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));

}});
