Java题库练习!!!
System.out.println("Before Copying:");
for (int i = 0;i<10;i++)
{
a[i]= i+1;
b[i] = (i+1)*100;
System.out.print("b["+i+"]=" +b[i] + " "); }
System.out.println("");
System.arraycopy(a,2,b,5,5);
System.out.println("After Copying:");
for (int i = 0;i<b.length;i++)
{
System.out.print("b["+i+"]=" + b[i] + " "); }
}
}
知识点：线程
1．本程序利用线程显示1-99之间的数
public class TestThread extends Thread {
public void run()
{
for(int i = 0;i<100;i++)
System.out.println("Count:"+i);
}
public static void main(String[] args)
{
