代码如下: Stringresult=sb.toString(); 1. 完整代码示例 下面是将Java数组转换为字符串的完整代码示例: int[]array={1,2,3,4,5};StringBuildersb=newStringBuilder();for(inti=0;i<array.length;i++){sb.append(array[i]);}Stringresult=sb.toString(); 1. 2. 3. 4. 5. 6. 7. 8. 总结 通过...
publicclassTest6{publicstaticvoidmain(String[] args){int[] array = {1,2,3,4,5,6}; System.out.println(Arrays.toString(array)); } } 格式化输出结果如下 [1, 2, 3, 4, 5, 6]
String str3 = new String("hello"); System.out.println(str1.equals(str2)); System.out.println(str1.equals(str3)); 1. 2. 3. 4. 5. 运行结果是: 分析:在上面的示例中str1和str2都是字符串常量,它们的地址相同,所以结果返回第4行返回的结果是true(说明:在Java中,字符串常量是被放在常量池当中...
import java.util.Arrays;public class ArrayToString1{ public static void main(String[] args) { int[] array = {1, 2, 3, 4, 5};String newArray = Arrays.toString(array);System.out.println("newArray="+newArray);} ⽅法⼆：思考思路：⾃⼰实现转化⽅法，注意字符串拼接 代码实现：publ...

JDK中提供了一个专门用于操作数组的工具类,即Arrays类,位于java.util 包中。 常用方法 示例代码 复制 publicclass Test {publicstatic void main(String[]args){inta[]={12,20,13,42,72,26,35,10,46,26,53};intb[]={3,5,7,8,54,23,9};intc[]={3,5,7,8,54,23,9};String str=Arrays.toStr...
方式一:String s1 = ""+number; 方式二:String s2 = String.valueOf(number); //返回int参数字符串表示形式,该方法是String类中的方法 String--int转换: String number = "111"; 方式一:Integer i = Integer.valueOf(number); int x = i.intValue(); ...
java.lang.String :此类不需要导入。 代码如下: 代码语言:javascript 复制 public static void main(String[] args) { //1.String() 创建一个空的字符串对象 String str1=new String(); System.out.println("str1: "+str1); // 2.String(String original) 根据字符串来创建一个字符串对象 String str2...
static String deepToString(Object[] a) Returns a string representation of the "deep contents" of the specified array. static boolean equals(boolean[] a, boolean[] a2) Returns true if the two specified arrays of booleans are equal to one another. static boolean equals(byte[] a, byte[]...
