用 Java 编写一个程序，将数组转换为字符串?
java 8object oriented programmingprogramming更新于 2025/9/5 15:08:17
java.util 包中的 Arrays 类提供了一个名为 toString() 的方法，该方法接受一个数组值(任意类型)并返回一个字符串。
示例
以下 Java 程序从用户那里接受各种数组，将它们转换为字符串值并打印结果。
import java.util.Arrays;
import java.util.Scanner;
public class ObjectArrayToStringArray {
public static void main(String args[]){
Scanner sc = new Scanner(System.in);
//Integer array to String
System.out.println("Enter 5 integer values: ");
int intArray[] = new int[5];
for(int i=0; i<5; i++){
intArray[i] = sc.nextInt();
}
System.out.println("Contents of the integer array: "+Arrays.toString(intArray));
//float array to String
System.out.println("Enter 5 float values: ");
float floatArray[] = new float[5];
for(int i=0; i<5; i++){
floatArray[i] = sc.nextFloat();
}
System.out.println("Contents of the float array: "+Arrays.toString(floatArray));
//double array to String
System.out.println("Enter 5 double values: ");
double doubleArray[] = new double[5];
for(int i=0; i<5; i++){
doubleArray[i] = sc.nextDouble();
}
System.out.println("Contents of the double array: "+Arrays.toString(doubleArray));
//byte array to String
System.out.println("Enter 5 byte values: ");
byte byteArray[] = new byte[5];
for(int i=0; i<5; i++){
byteArray[i] = sc.nextByte();
}
System.out.println("Contents of the byte array: "+Arrays.toString(byteArray));
//char array to String
System.out.println("Enter 5 character values: ");
char charArray[] = new char[5];
for(int i=0; i<5; i++){
charArray[i] = sc.next().toCharArray()[0];
}
System.out.println("Contents of the char array: "+Arrays.toString(charArray));
//object array to String
System.out.println("Enter 5 String values: ");
Object objArray[] = new Object[5];
for(int i=0; i<5; i++){
objArray[i] = sc.next();
}
System.out.println("Contents of the object array: "+Arrays.toString(objArray));
}
}
输出
Enter 5 integer values: 14 12 63 78 96 Contents of the integer array: [14, 12, 63, 78, 96] Enter 5 float values: 2.1 3.2 14.3 6.1 3.2 Contents of the float array: [2.1, 3.2, 14.3, 6.1, 3.2] Enter 5 double values: 1254.3256 1458.2354 1478.24 14587.325 1457.325 Contents of the double array: [1254.3256, 1458.2354, 1478.24, 14587.325, 1457.325] Enter 5 byte values: 1 25 61 11 24 Contents of the byte array: [1, 25, 61, 11, 24] Enter 5 character values: a b c d e Contents of the char array: [a, b, c, d, e] Enter 5 String values: hello hi bye welcome thankyou Contents of the object array: [hello, hi, bye, welcome, thank you]
