如何在Java中将方法的结果转换为字符串？

int result = 10;
String strResult = String.valueOf(result);

public class MyClass {
    private int value;

    public MyClass(int value) {
        this.value = value;
    }

    @Override
    public String toString() {
        return "MyClass{" +
                "value=" + value +
                '}';
    }
}

MyClass obj = new MyClass(10);
String strObj = obj.toString();

int a = 5;
int b = 3;
StringBuilder sb = new StringBuilder();
sb.append("The sum of ").append(a).append(" and ").append(b).append(" is ").append(a + b);
String result = sb.toString();
