What should you pay attention to when using the java program counter?

1. In the Java virtual machine specification, the program counter area does not specify any OutOfMemoryError situation.

2. Thread privateity, each thread has a private program counter inside.

Its life cycle is created when the thread is created and dies when the thread ends.

3. When a thread is executing a Java method, this counter records the address of the virtual machine bytecode instruction being executed.

If the Native method is being implemented, the counter value is empty (Undefined).

Example

package com.java.se;
 
public class Test {
 
public static void main(String[] args) {
int a=10;
int b=20;
if(a>=b)
System.out.println(a);
else
System.out.println(b);
 
}
 
}
