题目如下:
public static void main(String[] args) { int a=10; int b=10; method(a, b); System.out.println("a***"+a); System.out.println("b***"+b); }
如何打印出
a***1000b***1000
方法一:
public static void method(int a,int b) { a = a*100; b = b*100; System.out.println("a***"+a); System.out.println("b***"+b); System.exit(0);//退出虚拟机 }
方法二:
public static void method(int a, int b) { PrintStream Sys = new PrintStream(System.out){ @Override public void println(String x) { super.println("a="+a*100+", b="+b*100); } }; System.setOut(Sys); // try { // System.setOut(new PrintStream(new FileOutputStream("D:\\a.txt"))); // } catch (FileNotFoundException e) { // e.printStackTrace(); // } }
