When doing the project, I encountered the need to convert the year (String) into int type, compare the years, extract them as methods by the way, and save them for later use.
public class ConvertUtil {
// Put String Convert to float
public static float convertToFloat(String number, float defaultValue) {
if (TextUtils.isEmpty(number)) {
return defaultValue;
}
try {
return Float.parseFloat(number);
} catch (Exception e) {
return defaultValue;
}
}
// Put String Convert to double
public static double convertToDouble(String number, double defaultValue) {
if (TextUtils.isEmpty(number)) {
return defaultValue;
}
try {
return Double.parseDouble(number);
} catch (Exception e) {
return defaultValue;
}
}
// Put String Convert to int
public static int convertToInt(String number, int defaultValue) {
if (TextUtils.isEmpty(number)) {
return defaultValue;
}
try {
return Integer.parseInt(number);
} catch (Exception e) {
return defaultValue;
}
}
}
When you use it, you only need to call the above method (the second parameter is the default value):
int yeatInt = ConvertUtil.convertToInt("2017",2015);
