Java程序将原始类型值转换为字符串
为了将原始类型值转换为Java中的字符串，请使用valueOf()方法。假设我们要将以下双精度原始类型转换为字符串。
double val4 = 8.34D;
为此，请使用valueOf()方法。它将其转换为字符串。
String str4 = String.valueOf(val4);
示例
public class Demo {
public static void main(String[] args) {
int val1 = 5;
char val2 = 'z';
float val3 = 9.56F;
double val4 = 8.34D;
System.out.println("Integer: "+val1);
System.out.println("Character: "+val2);
System.out.println("Float: "+val3);
System.out.println("Double: "+val4);
String str1 = String.valueOf(val1);
String str2 = String.valueOf(val2);
String str3 = String.valueOf(val3);
String str4 = String.valueOf(val4);
System.out.println("\nConverted to string...");
System.out.println(str1);
System.out.println(str2);
System.out.println(str3);
System.out.println(str4);
}
}输出结果
Integer: 5 Character: z Float: 9.56 Double: 8.34 Converted to string... 5 z 9.56 8.34
