使用JDBC查询后,可利用以下方法: 隐藏高级命令 ```java import java.math.BigDecimal; AI检测代码解析 public class NumberToStringConverter { public static String convert(BigDecimal number) { return number.toString(); } } ``` 验证测试: 为确保转换后的数据在应用中的性能表现符合要求,我们进行了性能压...
首先,我们需要创建一个NumberToStringConverter类来完成转换的操作。该类包含一个数字集合和一个字符串集合,以及一个convert方法用来执行转换。 AI检测 importjava.util.ArrayList;importjava.util.List;publicclassNumberToStringConverter{privateList<Integer>numbers;privateList<String>strings;publicNumberToStringConverter(...
String.valueOf(a)->Integer.toString(a)->IntegralToString.intToString(a)->convertInt(null, a) Integer.toString(a)->IntegralToString.intToString(a)->convertInt(null, a) 能够看到String.valueOf是通过调用Integer.toString实现的,也难怪他们的效率如此接近。 他们最后都会调用到convertInt函数中: privatestat...
There are several easy ways to convert a number to a string: int i; // Concatenate "i" with an empty string; conversion is handled for you. String s1 = "" + i; or // The valueOf class method. String s2 = String.valueOf(i); Each of the Number subclasses includes a class ...
5. Conclusion In this article, we learned how easy it is to convert aListto aStringusing different techniques. As always, the full source code for this article can be foundover on GitHub.

We can simply use thetoString()method of theLongclass to convert them toString: Stringstr1=Long.toString(l);Stringstr2=Long.toString(obj); System.out.println(str1); System.out.println(str2); The output will look like this: 10 15 ...

ThetoString()method is used to convertBigDecimaltoString. It is available in the java class that extends thejava.lang.objectclass. It returns the string number as String output. Syntax: BigDecimal.toString() code: MathContextm=newMathContext(3);BigDecimalbg=newBigDecimal("3617E+4",m);System.ou...
TheintValuemethod converts theIntegertoint. Likewise, thefloatValuereturns afloatdata type. String bin = Integer.toBinaryString(a); String hex = Integer.toHexString(a); String oct = Integer.toOctalString(a); These three methods return a binary, hexadecimal, and octal representation of the integ...
