termination of the given Bare JBC problem could be proven:

(0) Bare JBC problem
(1) BareJBCToJBCProof [EQUIVALENT, 96 ms]
(2) JBC problem
(3) JBCToGraph [EQUIVALENT, 155 ms]
(4) JBCTerminationGraph
(5) TerminationGraphToSCCProof [SOUND, 0 ms]
(6) TRUE

(0)
Obligation:
need to prove termination of the following program:
package example_4;

public class Examples {
	
	int f = 10;

	// usual getter and setter methods
	public int getF() {
		return f;
	}

	public void setF(int f) {
		this.f = f;
	}
	
}


package example_4;
