sum=a+b;
diff=c-b;
System.out.println(sum,diff);
}

Explanation
- public is a keyword so it can't be used as an identifier for naming the class. Change the class name from public to any valid identifier, for example
class Sample - Argument of main method is an array of Strings. Use square brackets instead of curly brackets —
String args[] - c is an int variable. We cannot assign a double literal 65.45 to it.
- Variables sum & diff are not defined
- The line
System.out.println(sum,diff);should be written like thisSystem.out.println(sum + " " + diff);
Corrected Program
class Sample //1st correction
{
public static void main(String args[]) //2nd correction
{
int a=45,b=70,c=65; //3rd correction
int sum=a+b; //4th Correction
int diff=c-b;
System.out.println(sum + " " + diff); //5th Correction
}
}
