Android String类型转换为float、double和int的工具类方法

public class ConvertUtil { 	//把String转化为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;		} 	} 	//把String转化为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;		} 	} 	//把String转化为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;		}	}}

int yeatInt = ConvertUtil.convertToInt("2017",2015);
