java - 从数组中删除括号

Question

我希望这个数组在被 main 方法调用时打印时不带括号。

public static void main(String[] args) {    
    int [] temps = {15, 43, 23, 20}; 
    System.out.print(Arrays.toString(arrayIncrease(temps)));
}

public static int[] arrayIncrease (int[] array) {

    int [] tempsUp = new int[array.length];    
    for (int i = 0; i < array.length; i++)     
        tempsUp[i] = array[i] + 10; 

    return tempsUp; 
}

电流输出

[25, 53, 33, 30]

您可以使用 substring 来提取字符串中括号内的部分:

String output = Arrays.toString(arrayIncrease(temps);
System.out.print(output.substring(1, output.length() - 1);
