如何让对象的自定义构建器设置几个字段？

public class MyClass {
    private String field1;
    private int field2;
    private boolean field3;

    private MyClass(String field1, int field2, boolean field3) {
        this.field1 = field1;
        this.field2 = field2;
        this.field3 = field3;
    }

    public static Builder builder() {
        return new Builder();
    }

    public static class Builder {
        private String field1;
        private int field2;
        private boolean field3;

        public Builder field1(String field1) {
            this.field1 = field1;
            return this;
        }

        public Builder field2(int field2) {
            this.field2 = field2;
            return this;
        }

        public Builder field3(boolean field3) {
            this.field3 = field3;
            return this;
        }

        public MyClass build() {
            return new MyClass(field1, field2, field3);
        }
    }
}

MyClass obj = MyClass.builder()
                    .field1("value1")
                    .field2(10)
                    .field3(true)
                    .build();
