public static void main(String [] args)
int j=10;
System.out.println("j is : "+j);
calculate(j);
System.out.println("At last, j is : "+j);

static void calculate (int j)
for (int i = 0;i<10;i++)
j++;
System.out.println("j in calculate() is: "+j);


输出结果为：
j is : (1)
j in calculate() is : (2)
At last j is : (3)
