class Echo
{
public static void main (String[] args) throws IOException
{
InputStreamReader inStream =new InputStreamReader( System.in ) ;
BufferedReader stdin =new BufferedReader( inStream );
String inData;
System.out.println("Enter the data:");
inData = stdin.readLine();
System.out.println("You entered:" + inData );
}
}
Output:
Enter the data: Hi. . Welcome to E.S
You entered: Hi. . Welcome to E.S
Result:
Thus the implementation of JAVA program for Java I/O program is executed and the output has been verified.
Ex: No: 15 DESIGN MULTITHREAD PROGRAM IN JAVA
Aim:
To write a JAVA programs to implement the design multithread program.
Algorithm:
Step 1: Start the program.
Step 2: Create the thread class.
Step 3: Create the main class thread.
Step 4: Create the memory space.
Step 5: Execute the program.
Step 6: Display the output.
Step 7: Stop the program
Program:
public class CurrentThreadDemo1
{
public static void main(String args[])
{
Thread t=Thread.currentThread();
System.out.println("current thread:"+t);
t.setName("my thread");
System.out.println("after name change:"+t);
try
{
for(int n=5;n>0;n--)
{
System.out.println(n);
Thread.sleep(1000);
}
}
catch(InterruptedException ie)
{
System.out.println("main thread interrupted");
}
}
}
Output:
Current Thread: Thread [Main, 5, Main]
After Name Change: Thread [My Thread, 5, Main]
5
4
3
2
1
Result:
Thus the implementation of JAVA program for design multithread program is executed and the output has been verified.
