To create a String from byte array in Java, create a new String object with String() constructor and pass the byte array as argument to the constructor. In the following example, we will take a byte array{65, 66, 67, 68}and create a new stringstrfrom this byte array. ...
intArray1=newint[]{0,1,2}; 使用new创建数组对象但是分配数组时会自动为数组分配默认值,具体如下: System.out.println("intArray0[0]="+intArray0[0]); floatArray0=newfloat[3]; System.out.println("floatArray0[0]="+floatArray0[0]); ...
ossClient.putObject(url,newByteArrayInputStream("Hello OSS".getBytes()), -1, header); 未指定Method参数时,默认使用GET方法。以上为PutObject请求,应指定Method参数并设置为PUT方法。 通过PutObject发送请求时,请求Header中自定义的元数据必须以x-oss-meta-为前缀。以上示例中自定义元数据应改为x-oss-meta-auth...
