Besides Stringbuffer is already synchronized , but it is only in method5 called , and this according to the correct solution doesn't mean that method5 must be synchronized as well .
package de.codegym.task.task17.task1716;
/*
Synchronisierte Methoden
*/
public class Solution {
private double param = Math.random();
private StringBuilder sb = new StringBuilder();
private void method0() {
Double d = method3();
}
protected void method1(String param1) {
Solution solution = new Solution();
solution.method0();
}
public void method2(int param1) {
param1++;
}
double method3() {
double random = Math.random();
param += 40.7;
return random + param;
}
private void method4() {
sb.append(1).append(1).append(1).append(1);
}
protected void method5(String param2) {
new StringBuffer().append(param2).append(param2).append(param2);
}
public String method6(int param2) {
System.out.println("Denken....");
method7(5e-2);
sb = new StringBuilder("Alles klar!");
return sb.toString();
}
String method7(double param2) {
return "" + param2;
